Correct Answer: C

Rationale: The correct instruction to prevent hip dislocation after total hip arthroplasty is to avoid crossing the legs at the knees. This position can put stress on the hip joint and increase the risk of dislocation. Choices A, B, and D are incorrect. Bending the hip more than 90 degrees, lying on the unaffected side, or keeping the legs in a neutral position are not directly related to preventing hip dislocation in this context.

Correct Answer: D

Rationale: A heart rate of 146/min is abnormal for a preschooler and indicates tachycardia, which should be reported to the provider. Choices A, B, and C fall within normal ranges for a preschooler's heart rate (80-120/min) and respiratory rate (22-34/min), so they do not require immediate reporting. Option D is the correct answer as it deviates significantly from the normal range and may indicate an underlying health issue that needs attention.

Correct Answer: A

Rationale: The correct answer is A: Crush medications and mix with food. When administering oral medications to a patient with dysphagia, crushing the medications and mixing them with food is a common method to aid in swallowing. Choice B is incorrect because using a straw could pose a choking hazard for patients with dysphagia. Choice C is incorrect as thickened liquids may not always be suitable for all medications. Choice D is incorrect because having the patient lie flat can increase the risk of aspiration, which is not recommended for patients with dysphagia.

Correct Answer: B

Rationale: The correct first action for a client with a serum albumin level of 3 g/dL and a pressure ulcer is to consult a dietitian to improve the client's nutritional status. Adequate nutrition is essential for wound healing. Monitoring fluid and electrolyte balance is important but not the first priority in this situation. Administering a protein supplement can be considered after dietary evaluation. Administering an anti-inflammatory medication is not the primary intervention for addressing a pressure ulcer related to low albumin levels.

Correct Answer: A

Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.
