Correct Answer: A

Rationale: The best position for a patient with respiratory distress is the Semi-Fowler's position. This position promotes lung expansion and improves oxygenation by allowing the chest to expand more fully. The Trendelenburg position, where the patient's feet are higher than the head, is contraindicated in respiratory distress as it can increase pressure on the diaphragm and compromise breathing. The prone position, lying face down, may be beneficial in certain cases like acute respiratory distress syndrome but is not generally recommended for all patients in respiratory distress. The supine position, lying flat on the back, can worsen respiratory distress by causing the tongue to fall back and obstruct the airway.

Correct Answer: A

Rationale: Administering anticoagulants is the most crucial nursing action for a patient experiencing a deep vein thrombosis (DVT). Anticoagulants help prevent further clot formation and reduce the risk of complications such as pulmonary embolism. Encouraging ambulation, applying compression stockings, and monitoring oxygen saturation are important interventions in managing DVT, but administering anticoagulants takes priority as it directly targets the clotting process and prevents clot progression.

Correct Answer: A

Rationale: The correct answer is to 'Check daily weight.' Monitoring daily weight is the most accurate method to assess for fluid overload in patients with heart failure. Weight gain can indicate fluid retention, a common issue in heart failure patients. Checking blood pressure (Choice B) can provide information about hemodynamic status but may not be as specific for fluid overload as monitoring weight. Monitoring heart sounds (Choice C) can provide information about cardiac function but may not directly assess fluid overload. Assessing for jugular vein distention (Choice D) can be a sign of increased central venous pressure but may not always correlate with fluid overload as accurately as daily weight checks.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which is paleness of the skin, is a common sign of anemia due to a decreased number of red blood cells or hemoglobin levels. This results in reduced oxygen-carrying capacity, leading to the paleness of the skin. Choice A, increased appetite, is not typically associated with anemia. Choice C, tachycardia (increased heart rate), can be present in anemia as the body compensates for decreased oxygenation. Choice D, hypertension (high blood pressure), is not a common finding in anemia; instead, low blood pressure may be observed due to decreased blood volume.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid lying down after meals.' This instruction is important for clients with GERD to prevent acid reflux. Lying down after meals can worsen GERD symptoms by allowing stomach acid to flow back into the esophagus. Choices A, C, and D are incorrect. Choice A is incorrect because lying flat after meals can increase the risk of acid reflux. Choice C is incorrect because hot liquids may aggravate GERD symptoms. Choice D is incorrect because consuming a high-carbohydrate snack at bedtime can also trigger acid reflux in individuals with GERD.
