Correct Answer: C

Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.

Correct Answer: D

Rationale: The correct answer is D: Administer 15 grams of a fast-acting carbohydrate. The first step in treating hypoglycemia is to quickly raise the client's blood sugar level. Fast-acting carbohydrates like glucose tablets or juice are essential for this purpose. Giving a glucagon injection is typically reserved for severe hypoglycemia when the client is unable to take anything by mouth. Encouraging the client to eat a high-protein snack is not appropriate for immediate treatment of hypoglycemia. Rechecking the blood glucose level in 15 minutes is important after administering the fast-acting carbohydrate to ensure that the blood sugar has returned to a safe level.

Correct Answer: C

Rationale: The most important instruction for the nurse to provide to a client scheduled for a colonoscopy and prescribed a bowel preparation is to take the entire bowel preparation as directed. Completing the entire bowel preparation as prescribed is crucial to ensure the colon is properly cleansed for the colonoscopy. Incomplete bowel prep can interfere with the visualization of the colon, leading to inaccurate results. Choices A, B, and D are important but not as crucial as ensuring the complete intake of the bowel preparation for an effective procedure.

Correct Answer: B

Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen via nasal cannula. Oxygen therapy is the priority intervention for a client with COPD experiencing increasing shortness of breath. It helps improve oxygenation and relieve respiratory distress. Choice B is not the priority as oxygenation needs to be addressed first. Choice C, chest physiotherapy, may be beneficial but is not the immediate priority in this situation. Choice D, encouraging the client to cough and deep breathe, is not the priority intervention when oxygenation is compromised.
