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. Which principle does not follow neuromaturational theory?

• A. The sequence and rate of motor development are consistent among infants
• B. Movement emerges from an interaction and cooperation of many systems
• C. Movement progresses from primitive reflexes to voluntary control
• D. Low-level skills are prerequisites for certain high-level skills

Correct answer: B

Rationale: Neuromaturational theory emphasizes that motor development progresses in a predictable sequence and rate, starting from primitive reflexes to voluntary control. It also states that low-level skills are foundational for higher-level skills. However, the theory does not support the idea that movement solely emerges from an interaction and cooperation of many systems, as it focuses more on the hierarchical development of motor skills.

3. Which assessment finding for a 4-month-old infant would require further action by the nurse?

• A. The posterior fontanel is open.
• B. The infant has good head control when held upright.
• C. The infant is able to roll only from abdomen to back.
• D. The anterior fontanel is open and soft.

Correct answer: A

Rationale: The correct answer is A. The posterior fontanel should be closed by 4 months of age. An open posterior fontanel at this age may indicate a delay in normal closure, which could be a cause for concern and require further evaluation by the healthcare provider to ensure proper development and growth. Choices B, C, and D are typical developmental milestones for a 4-month-old infant and do not raise immediate concerns requiring further action by the nurse.

4. As a result of opioid administration, a child's respirations are slow and shallow. Which should the nurse anticipate when assessing the child's arterial blood gas?

• A. Increased PCO2 and respiratory acidosis
• B. Decreased PCO2 and respiratory alkalosis
• C. Low pH and low PCO2
• D. High pH and high PCO2

Correct answer: A

Rationale: When a child's respirations are slow and shallow due to opioid administration, it results in hypoventilation. This leads to retaining carbon dioxide, indicated by an increased PCO2 level on arterial blood gas analysis, and subsequently causes respiratory acidosis due to the buildup of CO2 in the blood. Therefore, choice A, 'Increased PCO2 and respiratory acidosis,' is the correct answer. Choices B, C, and D are incorrect because slow and shallow respirations would not lead to decreased PCO2 or respiratory alkalosis (choice B), low pH and low PCO2 (choice C), or high pH and high PCO2 (choice D).

5. What is the recommended sleep duration for 14-17-year-olds?

• A. 14-17 hours
• B. 8-10 hours
• C. 12-15 hours
• D. 9-11 hours

Correct answer: B

Rationale: The recommended sleep duration for adolescents aged 14-17 is 8-10 hours to promote optimal health. Getting enough sleep is crucial for their physical and mental well-being, as it supports growth, development, learning, and overall health.
