Correct Answer: C

Rationale: The correct answer is C: Fresh or frozen vegetables without sauce. These foods are low in sodium, which is crucial for managing hypertension. Pickled olives (choice A) and canned soup (choice B) are high in sodium, which can exacerbate hypertension. While fruits without sauce (choice D) are generally healthy, emphasizing vegetables is more beneficial for hypertension due to their lower sodium content.

Correct Answer: A

Rationale: Administering oxygen at 2 L/min via nasal cannula is the nurse's first action when a client with COPD presents with a respiratory rate of 32 breaths per minute and an oxygen saturation of 86%. Oxygen therapy helps improve oxygen saturation in patients with COPD and respiratory distress. While notifying the healthcare provider is important, immediate intervention to improve oxygenation takes priority. Positioning the client in high Fowler's position can also assist with breathing but is not the initial action in this scenario. Suctioning the airway is not indicated unless there are secretions obstructing the airway, which is not mentioned in the scenario.

Correct Answer: B

Rationale: Obtaining a detailed health and dietary history is crucial when assessing constipation in elders. This helps the nurse identify potential causes such as inadequate fluid intake, low fiber diet, lack of physical activity, or medications that could be contributing to constipation. A complete blood count (Choice A) is not the priority in the initial assessment of constipation. Referring to a provider for a physical examination (Choice C) would be done after gathering more information from the health history. Measuring height and weight (Choice D) is not directly relevant to assessing constipation and identifying its causes.

Correct Answer: B

Rationale: The correct teaching for a client prescribed metformin includes monitoring renal function regularly due to the risk of lactic acidosis, especially in clients with impaired kidney function. While taking metformin with meals can reduce gastrointestinal upset, it is not the highest priority teaching point. Avoiding alcohol is generally recommended but not the most critical teaching point in this scenario. Checking blood glucose levels regularly is important for diabetes management but not specifically related to metformin use.

Correct Answer: B

Rationale: The correct answer is B: To maintain straight spinal alignment. Logrolling is a technique used to carefully turn a client while keeping the spine in a straight line, especially important for those with spinal injuries or after back surgery. Choice A is incorrect because the primary purpose is not specifically to decrease the risk of back injury but to ensure safe turning. Choice C is incorrect as the main aim is not to increase client safety by using multiple people but to protect the spine. Choice D is incorrect because the primary purpose of logrolling is not to prevent skin damage but to safeguard the spine during turning.
