1. For which patient diagnosis would a prescription for nifedipine be least appropriate?

• A. Angina Pectoris
• B. Essential HTN
• C. Atrial Fibrillation
• D. Vasospastic Angina

Correct answer: C

Rationale: Nifedipine primarily acts as a calcium channel blocker, exerting its effects on vascular smooth muscle. It is not effective for treating dysrhythmias like Atrial Fibrillation, which involve abnormalities in the heart's electrical system. Nifedipine is commonly prescribed for conditions such as angina pectoris, essential hypertension, and vasospastic angina due to its vasodilatory and anti-anginal properties. Choices A, B, and D are more appropriate as nifedipine can help in managing angina pectoris, hypertension, and vasospastic angina by reducing myocardial oxygen demand and dilating coronary arteries.

2. A child is being treated for dehydration with intravenous fluids. The child currently weighs 13 kg and is estimated to have lost 7% of his normal body weight. The nurse is double-checking the IV rate the healthcare provider prescribed. The formula the healthcare provider used was for maintenance fluids: 1000 mL for 10 kg of body weight plus 50 mL for every kilogram over 10 for 24 hours. Replacement fluid is the percentage of lost body weight � 10 per kg of body weight. According to the calculation for maintenance plus replacement fluid, which hourly IV rate will the nurse implement for 24 hours?

• A. 88 mL/hr
• B. 86 mL/hr
• C. 81 mL/hr
• D. 83 mL/hr

Correct answer: B

Rationale: For 13 kg, the maintenance fluid is 1150 mL (1000 mL for first 10 kg + 3*50 mL for the remaining 3 kg). Replacement fluid is 910 mL (0.07 * 13000 mL). Total fluid is 2060 mL, divided by 24 hours is 86 mL/hr.

3. A nurse in an emergency department is caring for a school-age child who is experiencing an anaphylactic reaction. Which of the following is the priority action by the nurse?

• A. Elevate the head of the child's bed
• B. Insert a large-bore IV catheter for the child
• C. Determine the allergen that caused the child's reaction
• D. Administer IM epinephrine to the child

Correct answer: D

Rationale: In the management of anaphylaxis, the priority action for the nurse is to administer IM epinephrine to the child. Epinephrine is the first-line treatment for anaphylaxis as it helps reverse the severe manifestations of the reaction by constricting blood vessels, relaxing airway muscles, and decreasing hives and swelling. Elevating the head of the child's bed may be beneficial for respiratory distress but is not the priority over administering epinephrine. Inserting a large-bore IV catheter may be necessary for fluid resuscitation but is not the initial priority. Identifying the allergen is important for prevention and future management but is not the immediate action needed in the acute phase of an anaphylactic reaction.

4. The patient with bipolar disorder is being treated with lithium and has a new prescription for captopril for hypertension. The combination of these two drugs makes which assessment particularly important?

• A. Potassium level
• B. Lithium level
• C. Creatinine level
• D. Blood pressure

Correct answer: B

Rationale: When captopril, an ACE inhibitor, is combined with lithium, it can lead to lithium accumulation. Therefore, monitoring lithium levels is crucial to prevent toxicity. While ACE inhibitors like captopril can cause hyperkalemia, renal insufficiency, and hypotension, the risk of these effects is not increased by the combination of lithium and captopril.

5. The healthcare provider is providing teaching about Social Development to the parents of a preschooler. Which of the following play activities should the provider recommend for the child?

• A. Playing pat-a-cake
• B. Using a push-pull toy
• C. Creating a scrapbook
• D. Playing dress-up

Correct answer: D

Rationale: During the preschool age, play activities should promote social, mental, and physical development. Playing dress-up encourages imagination, creativity, and social interaction, making it an ideal play activity for preschoolers.
