Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In CKD, kidneys struggle to excrete potassium, leading to its accumulation in the blood. This can result in dangerous cardiac arrhythmias. Hypokalemia (B) is unlikely in CKD due to impaired potassium excretion. Hyperglycemia (C) is more commonly associated with diabetes rather than CKD. Hypercalcemia (D) is not a typical complication of CKD; instead, patients with CKD often experience low calcium levels.

Correct Answer: D

Rationale: The correct answer is D because a health history aims to gather subjective information about a patient's past and current health. It helps in understanding the patient's health concerns, medical history, lifestyle factors, and other relevant information. By collecting this data, healthcare providers can make informed decisions regarding the patient's care. Option A is incorrect as the purpose is more than just interaction. Option B is incorrect as it focuses solely on biographical information. Option C is incorrect as it pertains to physical assessment findings, not subjective health information.

Correct Answer: B

Rationale: The correct answer is B: Encouraging early ambulation. This is because early ambulation is crucial in preventing complications such as blood clots and muscle atrophy post hip replacement surgery. It helps improve circulation, prevent joint stiffness, and promote healing. Administering pain medication regularly (A) is important but not the top priority. Providing wound care and dressing changes (C) and monitoring for signs of infection (D) are also important but secondary to early ambulation in preventing complications and promoting recovery.

Correct Answer: D

Rationale: The correct answer is D: Respiratory failure. In chronic asthma, persistent inflammation and airway remodeling can lead to worsening lung function and respiratory distress, ultimately resulting in respiratory failure. Monitoring for signs of respiratory distress such as increased work of breathing, decreased oxygen saturation, and altered mental status is crucial. A: Hypoglycemia is not a typical complication of asthma. B: Oxygen toxicity is not a common complication in asthma management unless high concentrations of supplemental oxygen are administered for prolonged periods. C: Hyperkalemia is not directly associated with asthma but may occur as a complication of certain asthma treatments or comorbid conditions. Therefore, the priority complication to monitor in a patient with chronic asthma is respiratory failure due to the progressive nature of the disease and the potential for acute exacerbations.

Correct Answer: C

Rationale: The correct answer is C: A complete health database because of the nurse's primary responsibility for monitoring the patient's health. In this initial home visit, the nurse needs to gather comprehensive information about the patient's medical history, current health status, medications, allergies, and lifestyle factors to establish a baseline for ongoing care. This complete health database will help the nurse make informed decisions and provide personalized care. Choice A (follow-up database) is incorrect as it is used to evaluate changes over time, not for the initial assessment. Choice B (episodic database) is incorrect because the patient's chronic medical problems require a more comprehensive approach. Choice D (emergency database) is incorrect as it is used for urgent situations, not for routine assessments.
