Correct Answer: C

Rationale: The correct answer is C because decreasing fluid intake is essential in managing fluid retention and symptoms of heart failure. Restricting fluids helps prevent excessive fluid buildup in the body, thus reducing the workload on the heart and alleviating symptoms like swelling and shortness of breath. Choices A, B, and D are incorrect. Increasing intake of foods high in sodium can exacerbate fluid retention and worsen heart failure symptoms. Increasing potassium-rich foods is beneficial for some heart conditions but not heart failure specifically. Decreasing fiber intake is not a standard recommendation for heart failure management.

Correct Answer: B

Rationale: The correct answer is B. Administering an intramuscular injection at a 90° angle is essential for proper medication delivery into the muscle tissue. Injecting at a 45° angle is incorrect for intramuscular injections and is typically used for subcutaneous injections where the needle is inserted into the fatty tissue layer beneath the skin. Choice A is correct as selecting a 25-gauge needle is appropriate for an intramuscular injection. Choice C is also correct as the ventrogluteal site is a suitable site for intramuscular injections. Choice D is correct as aspirating for blood return is a necessary step to ensure the needle is not in a blood vessel before injecting the medication.

Correct Answer: C

Rationale: The correct instruction for the nurse to include during postoperative teaching following a hip arthroplasty is to 'Place a pillow between your legs when turning.' Placing a pillow between the legs when turning is crucial as it helps prevent dislocation of the hip prosthesis. This position aids in maintaining proper alignment and stability, thereby reducing the risk of complications after hip arthroplasty surgery. Choices A, B, and D are incorrect because they do not directly address the specific action needed to protect the hip prosthesis and prevent complications.

Correct Answer: B

Rationale: The correct answer is B. Avoiding coffee is important in managing peptic ulcer disease as it helps reduce acid production and alleviate symptoms. Coffee is known to stimulate acid secretion in the stomach, which can exacerbate ulcer symptoms. Therefore, instructing the client to avoid drinking coffee is essential in the dietary management of peptic ulcer disease. Choices A, C, and D are incorrect. Drinking milk is generally allowed and can even provide a protective effect against ulcers. High-fiber foods are beneficial for digestion and do not need to be avoided unless they cause discomfort. Low-fat foods are also typically recommended for individuals with peptic ulcer disease as they are easier on the digestive system.

Correct Answer: A

Rationale: The correct answer is A. Increasing intake of iodine-rich foods is beneficial for clients with hypothyroidism as iodine is essential for thyroid hormone synthesis. Adequate iodine intake helps to support thyroid function in individuals with hypothyroidism, making choice A the most appropriate response indicating an understanding of the dietary management for this condition. Choices B, C, and D are incorrect because decreasing iodine-rich foods, increasing potassium-rich foods, or decreasing sodium-rich foods are not the recommended dietary modifications for hypothyroidism. In fact, decreasing iodine-rich foods could exacerbate hypothyroidism due to the essential role of iodine in thyroid hormone production.
