1. One of the signs of CHF is shortness of breath. What is the term for shortness of breath when lying down?

• A. Platypnea
• B. Orthopnea
• C. Apnea
• D. Epistaxis

Correct answer: B

Rationale: Orthopnea is the specific term used to describe shortness of breath when lying down. This condition is commonly seen in patients with congestive heart failure (CHF) due to the redistribution of fluid in the body when changing positions. Platypnea refers to shortness of breath that worsens when sitting or standing, apnea is the cessation of breathing, and epistaxis is the medical term for a nosebleed. Therefore, the correct answer is B (Orthopnea).

2. Which of the following is MOST likely to occur in conjunction with a breech presentation?

• A. Vertex presentation
• B. Maternal hypertension
• C. Prolapsed umbilical cord
• D. Premature rupture of the amniotic sac

Correct answer: C

Rationale: In a breech presentation, where the baby's buttocks or feet present first, there is an increased risk of the umbilical cord slipping down alongside or below the presenting part, leading to a prolapsed umbilical cord. This is a serious complication that can compromise fetal blood flow and oxygenation, necessitating prompt intervention to prevent adverse outcomes. Choices A, B, and D are less likely to occur in conjunction with a breech presentation. Vertex presentation is the normal head-first presentation, maternal hypertension is a separate condition that may not be directly related to fetal presentation, and premature rupture of the amniotic sac can happen independently of the baby's presentation.

3. Warning signs that indicate dehydration include all EXCEPT:

• A. Poor skin turgor
• B. Increased urine output
• C. Tachycardia
• D. Eager to drink

Correct answer: B

Rationale: The correct answer is B. Increased urine output is not a warning sign of dehydration; it typically decreases with dehydration. Dehydration often presents with poor skin turgor, tachycardia, and an increased sensation of thirst (eager to drink) as the body tries to compensate for fluid loss. Choices A, C, and D are all correct warning signs of dehydration. Poor skin turgor is a result of decreased skin elasticity due to fluid loss. Tachycardia, an elevated heart rate, can be a compensatory mechanism to maintain cardiac output in dehydration. Feeling eager to drink is a common symptom of dehydration as the body attempts to restore fluid balance.

4. When assessing a 5-year-old boy with major trauma, his blood pressure is 70/40 mm Hg, and his pulse rate is 140 beats/min and weak. The child's blood pressure:

• A. indicates decompensated shock.
• B. reflects adequate compensation.
• C. suggests increased intracranial pressure.
• D. is appropriate based on his age.

Correct answer: A

Rationale: In a 5-year-old boy with major trauma, a blood pressure of 70/40 mm Hg and a pulse rate of 140 beats/min, and weak, indicate decompensated shock. This presentation signifies inadequate perfusion, leading to compensatory mechanisms being overwhelmed, resulting in decompensated shock. Choice B is incorrect as the vital signs suggest the body is unable to adequately compensate for the trauma. Choice C is incorrect as the vital signs are more indicative of shock rather than increased intracranial pressure. Choice D is incorrect as such low blood pressure is not appropriate for a child of this age and indicates a critical condition.

5. Atta, who weighs 20kg, has been prescribed amoxicillin 500 mg b.i.d. The drug information indicates a daily dose of amoxicillin at 50 mg/kg/day in two divided doses. What is the safest dose in milligrams for this child?

• A. 1000 mg
• B. 750 mg
• C. 500 mg
• D. 250 mg

Correct answer: A

Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.
