Correct Answer: A

Rationale: The correct answer is to assess the airway first. Ensuring a clear and patent airway is crucial to maintaining adequate oxygenation and ventilation post-surgery. Assessing the airway takes precedence over other assessments as a compromised airway can lead to hypoxia and respiratory distress. Checking blood pressure, the surgical site, or level of consciousness are important but are secondary to ensuring the airway is clear and the client can breathe effectively.

Correct Answer: C

Rationale: The correct answer is C. Limiting intake of beef to 4 ounces per week is an effective dietary modification to manage high cholesterol. Choice A is incorrect because the frequency and duration of exercise alone may not be sufficient to lower cholesterol significantly. Choice B is incorrect as proteins, including lean sources like poultry and fish, can be a part of a healthy diet. Choice D is incorrect as low-density lipoproteins, known as bad cholesterol, should be decreased, not increased, for heart health.

Correct Answer: A

Rationale: The correct way to use a cane is for the client to hold it on the stronger side of the body. This positioning allows the cane to provide support to the weaker side, assisting with balance and stability. Placing the cane on the weaker side (Choice B) may not provide adequate support and could lead to an increased risk of falls. Holding the cane in front of the weaker side (Choice C) or in front of the stronger side (Choice D) does not optimize the support and stability needed while walking with a cane.

Correct Answer: A

Rationale: The correct answer is A: Spinach. Spinach is high in oxalate, a compound that can contribute to the formation of calcium oxalate kidney stones. Therefore, advising the client to avoid spinach is crucial in reducing the risk of stone recurrence. Bananas (choice B) are not high in oxalate and do not directly contribute to the formation of calcium oxalate stones, so they do not need to be avoided. Similarly, choices C and D, chicken, and rice, are not typically associated with high oxalate content, making them safe choices and do not need to be avoided specifically to prevent calcium oxalate kidney stones.

Correct Answer: D

Rationale: The most important intervention for the LPN/LVN to implement for a male client experiencing urinary retention is to assess for bladder distention. This assessment is crucial as it helps identify the underlying cause of urinary retention, such as bladder distention or obstruction. By assessing the bladder, the LPN/LVN can determine the appropriate interventions needed, such as catheterization, medication administration, or further evaluation by the healthcare provider. Applying a condom catheter (Choice A) is more suitable for urinary incontinence, not retention. Applying a skin protectant (Choice B) is typically done to prevent skin breakdown in incontinent clients. Encouraging increased fluid intake (Choice C) may be beneficial for some urinary issues but is not the priority intervention for urinary retention.
