FMGE 2019 - Pediatrics FMGE Practice Questions and MCQs
Question 1: In marasmus, which of the following is characteristically seen?
- A. Hepatomegaly
- B. Edema
- C. Voracious appetite
- D. Severe muscle wasting (Correct Answer)
Explanation: ***Severe muscle wasting*** - **Severe muscle wasting** and **loss of subcutaneous fat** are hallmark features of marasmus, giving the child a characteristic **"skin and bones"** appearance. - Children present with **visible ribs**, **sunken cheeks**, and **prominent bony landmarks** due to depletion of both fat and muscle stores from chronic energy deficiency. *Hepatomegaly* - **Hepatomegaly** is a characteristic feature of **kwashiorkor**, not marasmus, caused by **fatty infiltration** of the liver due to impaired lipoprotein synthesis. - In marasmus, the liver is typically **normal or reduced in size** as fat stores are mobilized and utilized for energy needs. *Edema* - **Pitting edema** is a hallmark feature of **kwashiorkor**, resulting from severe protein deficiency causing **hypoalbuminemia** and reduced plasma oncotic pressure. - Marasmus is characterized by **absence of edema** because the protein deficiency is proportionally less severe compared to the overall caloric deficiency. *Voracious appetite* - Children with marasmus typically have **poor appetite** and **feeding difficulties**, not increased hunger, due to severe weakness and apathy. - The **energy depletion** and **muscle wasting** significantly reduce the child's interest in food and ability to consume adequate amounts.
Question 2: A child presents with complaints of bed wetting. What is the first line of treatment?
- A. Bed alarm technique (Correct Answer)
- B. Motivational therapy
- C. Oxybutynin
- D. Desmopressin
Explanation: ***Bed alarm technique*** - The **bed alarm technique** is considered the most effective first-line treatment for **nocturnal enuresis** in children. - It works through **classical conditioning**, training the child to wake up in response to bladder fullness. *Motivational therapy* - **Motivational therapy** can be a useful adjunct to other treatments, but it is not typically the sole **first-line therapy** due to varying effectiveness. - It focuses on building the child's confidence and encouraging dryness but does not directly address the physiological aspects of bedwetting. *Oxybutynin* - **Oxybutynin** is an anticholinergic medication that can reduce bladder contractions and increase bladder capacity. - It is usually reserved for cases where **bedwetting alarms** and **desmopressin** have been ineffective, or when there is an identifiable **overactive bladder component**. *Desmopressin* - **Desmopressin** is an antidiuretic hormone analogue that reduces urine production during the night. - While effective, it is often considered a **second-line treatment** after behavioral interventions like the bed alarm, or when rapid but temporary improvement is desired.
Question 3: Koplik spots are seen in?
- A. Rubella
- B. Mumps
- C. Varicella
- D. Measles (Correct Answer)
Explanation: ***Measles*** - **Koplik spots** are pathognomonic rash that appears as small, white spots with a bluish-white center on an erythematous base on the **buccal mucosa** opposite the second molars. - They typically appear 2-3 days before the onset of the characteristic maculopapular rash, during the **prodromal phase** of measles (rubeola). *Rubella* - Rubella, or **German measles**, presents with a milder rash, **lymphadenopathy**, and mild fever. - It does not cause Koplik spots; instead, **Forchheimer spots** (petechiae on the soft palate) may be seen, but these are less specific. *Mumps* - Mumps is characterized primarily by **parotitis** (swelling of the salivary glands), fever, and headache. - It does not present with Koplik spots or any characteristic oral mucosal lesions. *Varicella* - Varicella, or **chickenpox**, is characterized by a **vesicular rash** that progresses from macules to papules to vesicles to crusts, appearing in crops. - It does not involve Koplik spots; the rash is typically generalized and pruritic.
Question 4: Sixth disease is?
- A. Erythema nodosum
- B. Erythema marginatum
- C. Erythema Infectiosum
- D. Exanthema subitum (Correct Answer)
Explanation: ***Exanthema subitum*** - Exanthema subitum, also known as **Roseola infantum** or **sixth disease**, is a common childhood illness caused by human herpesvirus 6 (HHV-6) or less commonly HHV-7. - It is characterized by **3-5 days of high fever** followed by the abrupt appearance of a **maculopapular rash** once the fever subsides. *Erythema nodosum* - **Erythema nodosum** presents as tender, red nodules, typically on the shins, and is a type of **panniculitis** (inflammation of subcutaneous fat). - It is often associated with systemic diseases, infections (e.g., strep throat, tuberculosis), drugs, or inflammatory bowel disease, rather than being a primary childhood viral exanthem. *Erythema marginatum* - **Erythema marginatum** is a rare, transient, and non-pruritic rash with **serpiginous (snake-like) borders** that is a specific hallmark of **acute rheumatic fever**. - It is not a generalized viral exanthem and does not follow a typical febrile phase like sixth disease. *Erythema Infectiosum* - **Erythema infectiosum**, also known as **fifth disease**, is caused by **parvovirus B19** and is characterized by a "slapped cheek" rash on the face followed by a lacy rash on the trunk and extremities. - While it's a common childhood exanthem, it's distinct from sixth disease in its causative agent and characteristic rash pattern.
Question 5: For severe acute malnutrition in children (6-59 months), MAC will be less than
- A. 11.5 cm (Correct Answer)
- B. 13.5 cm
- C. 12.5 cm
- D. 14.5 cm
Explanation: ***11.5 cm*** - A **Mid-Upper Arm circumference (MUAC) below 11.5 cm** is a key diagnostic criterion for **severe acute malnutrition (SAM)** in children aged 6-59 months. - This measurement is a simple and effective screening tool in resource-limited settings to identify children at high risk of mortality due to malnutrition [1]. *13.5 cm* - A MUAC of 13.5 cm or greater is generally considered **nutritionally healthy** for children in this age group, indicating adequate muscle and fat reserves. - This measurement would typically rule out severe acute malnutrition and often even moderate malnutrition. *12.5 cm* - A MUAC between 11.5 cm and 12.5 cm is typically indicative of **moderate acute malnutrition (MAM)**, not severe acute malnutrition. - While concerning, it suggests a less critical nutritional status compared to a MUAC below 11.5 cm. *14.5 cm* - A MUAC of 14.5 cm or greater is well within the healthy range for children aged 6-59 months, indicating **good nutritional status**. - This measurement would suggest no signs of acute malnutrition.
Question 6: A 3-month-old baby presents with fever and respiratory rate of 60/min. The baby is irritable but feeding well. There is no stridor, no chest indrawing, and no convulsions. What is the diagnosis?
- A. Pneumonia (Correct Answer)
- B. Very severe pneumonia
- C. Severe pneumonia
- D. No Pneumonia
Explanation: ***Pneumonia*** - A respiratory rate of 60 breaths per minute in a 3-month-old infant meets the **WHO criteria for fast breathing**, which is the primary indicator for diagnosing **pneumonia** in this age group. - The absence of chest indrawing, stridor, or convulsions means this falls under **pneumonia**, not **severe** or **very severe pneumonia**. *Very severe pneumonia* - This would be diagnosed if there were **danger signs** such as inability to feed, lethargy, or convulsions, which are explicitly stated as absent. - Presence of **stridor** in a calm child or **severe malnutrition** would also suggest very severe pneumonia, none of which are mentioned. *Severe pneumonia* - This classification requires the presence of **chest indrawing** or **stridor** in a child, which are noted as absent in the clinical presentation. - While the child has fast breathing, the lack of additional severe signs distinguishes it from severe pneumonia. *No Pneumonia* - The presence of **fast breathing** (respiratory rate of 60 in a 3-month-old) is a clear sign of respiratory distress indicating **pneumonia**, according to WHO guidelines. - If the child had a normal respiratory rate and no other signs of respiratory illness, this option might be considered.
Question 7: Treatment of choice used in nocturnal enuresis is:
- A. Bed alarms (Correct Answer)
- B. Trazodone
- C. Fluoxetine
- D. Imipramine
Explanation: ***Bed alarms*** - **Bed alarms** are the **first-line, non-pharmacological treatment (TOC)** for nocturnal enuresis, working through classical conditioning to train the child to wake up when urination begins. - They have a high success rate and durable response once treatment is completed. *Trazodone* - **Trazodone** is an antidepressant primarily used for **insomnia** and depression; it is not indicated for the treatment of nocturnal enuresis. - It works by modulating serotonin reuptake and blocking alpha-1 adrenergic receptors, with a different mechanism of action than treatments for enuresis. *Fluoxetine* - **Fluoxetine** is a Selective Serotonin Reuptake Inhibitor (SSRI) primarily used to treat **depression, anxiety disorders**, and OCD. - It is not a recommended treatment for nocturnal enuresis and does not address the underlying physiological mechanisms. *Imipramine* - **Imipramine** is a tricyclic antidepressant that has been used for nocturnal enuresis, but it is **not the treatment of choice** due to potential side effects and the availability of safer, more effective options. - It works by anticholinergic and alpha-adrenergic effects to increase bladder capacity and arousal, but its use is often limited by its adverse effect profile.
