Correct Answer: A

Rationale: Corrected Rationale: Daily weight monitoring is crucial in managing patients with chronic heart failure as it helps assess fluid balance. Monitoring daily weight allows healthcare providers to detect any sudden weight gain, which could indicate fluid retention and worsening heart failure. This intervention helps in adjusting treatment plans promptly. Providing fluid restriction (Choice B) can be a part of managing heart failure but is not the primary intervention mentioned in the question. Administering diuretics (Choice C) is a treatment modality for heart failure but does not encompass the comprehensive approach to patient management. Monitoring intake and output (Choice D) is important but does not specifically address the direct assessment of fluid status as daily weight monitoring does.

Correct Answer: B

Rationale: The best position for a patient experiencing shortness of breath is the Semi-Fowler's position. This position promotes lung expansion and improves oxygenation by allowing the chest to expand more fully. The Supine position (lying flat on the back) may worsen breathing difficulties by reducing lung capacity. The Trendelenburg position (feet elevated higher than the head) is not recommended for patients with shortness of breath as it can increase pressure on the diaphragm and compromise breathing. The Prone position (lying face down) is also not suitable for patients experiencing shortness of breath as it may further restrict breathing.

Correct Answer: A

Rationale: The correct initial action for a patient with chest pain is to administer oxygen. Chest pain can be caused by insufficient oxygenation, and providing oxygen helps alleviate the pain by increasing oxygen levels in the blood. Administering nitroglycerin or morphine may be appropriate based on the underlying cause of the chest pain, but oxygen should be given first to ensure the patient's oxygen supply is adequate. Surgery is not typically the initial intervention for chest pain.

Correct Answer: D

Rationale: The correct answer is D: Weight. Weight monitoring is essential to assess the effectiveness of desmopressin therapy, as fluid retention is a common side effect. Monitoring fasting blood glucose (choice A) is not directly related to desmopressin therapy for diabetes insipidus. Monitoring carbohydrate intake (choice B) may be important in diabetes management but is not specific to desmopressin therapy. Hematocrit (choice C) monitoring is not a primary concern when managing diabetes insipidus with desmopressin.

Correct Answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.
