Correct Answer: D

Rationale: The correct answer is D because understanding the mother's pregnancy history can provide crucial insights into potential risk factors or exposures that could have contributed to the child's pneumonia. By knowing about the mother's smoking or drug use during pregnancy, the healthcare team can better assess the child's overall health and potential underlying conditions. Choice A is incorrect as it dismisses the importance of the question and fails to address the potential significance of the information. Choice B is incorrect as it downplays the relevance of the question, which is essential for gathering comprehensive information for the child's care. Choice C is incorrect as it makes an unsupported and potentially misleading statement about the direct cause of pneumonia without considering other factors.

Correct Answer: A

Rationale: The correct answer is A because it helps differentiate between orthopnea (difficulty breathing when lying down) and paroxysmal nocturnal dyspnea (sudden awakening due to difficulty breathing). By asking about worsening symptoms when lying down, the nurse can assess if the patient has orthopnea, a classic symptom of heart failure. Choices B, C, and D are incorrect because they do not specifically target the nighttime breathing difficulty associated with heart failure.

Correct Answer: B

Rationale: The correct answer is A: Eggs. Eggs are considered a complete protein because they contain all 9 essential amino acids required by the human body. This makes them a high-quality protein source. Corn (B), peanuts (C), and sunflower seeds (D) are not complete proteins as they lack one or more of the essential amino acids. Corn is deficient in lysine, peanuts are deficient in methionine, and sunflower seeds are deficient in lysine. Therefore, only eggs provide all the essential amino acids necessary for optimal health and proper bodily functions.

Correct Answer: C

Rationale: The correct answer is C: Placing the client on their back. This is the priority because it helps optimize the client's breathing mechanics by maximizing lung expansion. By positioning the client on their back, it allows for better oxygenation and ventilation. Administering oxygen (A) and albuterol (B) can be important interventions but positioning comes first. Placing the client on their back also helps prevent aspiration and facilitates airway clearance. Encouraging deep breathing (D) is beneficial, but if the client is in respiratory distress, ensuring proper positioning takes precedence over deep breathing exercises.

Correct Answer: D

Rationale: The correct answer is D because clinical practice guidelines for periodic health examinations provide a frequency schedule for health visits based on age. This is crucial for ensuring timely preventive care and monitoring of growth and development. Choice A is incorrect as guidelines focus on preventive care, not diagnosing illnesses. Choice B is incorrect because while guidelines may mention developmental milestones, their primary focus is on health maintenance. Choice C is incorrect as guidelines recommend health visits based on individual needs, not a one-size-fits-all annual physical examination.
