Correct Answer: A

Rationale: Administering oxygen is the best initial nursing intervention for a patient with suspected pulmonary embolism because it helps address hypoxia, a common complication of this condition. Oxygen therapy can improve oxygenation and support vital organ function. Administering anticoagulants (Choice B) is a treatment option for confirmed pulmonary embolism but not the initial intervention. Repositioning the patient (Choice C) and checking oxygen saturation (Choice D) are important assessments but do not address the immediate need to improve oxygenation in a patient with suspected pulmonary embolism.

Correct Answer: A

Rationale: Furosemide is the correct answer. It is a common diuretic used in patients with heart failure to reduce fluid overload. Metoprolol (Choice B) is a beta-blocker often prescribed to manage heart failure symptoms by improving heart function. Digoxin (Choice C) is used in heart failure patients to help the heart beat stronger and with a more regular rhythm. Aspirin (Choice D) is not typically prescribed for heart failure but may be used in patients with heart disease for its antiplatelet effects.

Correct Answer: D

Rationale: The correct answer is to apply a hydrocolloid dressing. For a stage 2 pressure injury, maintaining a moist environment is crucial for healing. Hydrocolloid dressings help achieve this by promoting autolytic debridement and creating a barrier against bacteria while allowing the wound to heal. Applying a dry dressing (Choice A) may not provide the necessary moisture for healing. Cleansing the wound with normal saline (Choice B) is essential, but a hydrocolloid dressing is more specific for promoting healing in this case. Performing debridement as needed (Choice C) is not typically indicated for stage 2 pressure injuries, as they involve partial-thickness skin loss without slough or eschar.

Correct Answer: A

Rationale: The correct answer is A: Using the Glasgow Coma Scale. The Glasgow Coma Scale is a standardized tool used to assess a patient's level of consciousness by evaluating their eye response, verbal response, and motor response. This scale provides a numeric value that helps in determining the severity of brain injury or altered mental status. Choices B, C, and D are incorrect because while assessing the patient's orientation, checking pupillary response, and monitoring vital signs are important components of a comprehensive patient assessment, they do not specifically target the assessment of consciousness level, which is best done using the Glasgow Coma Scale.

Correct Answer: D

Rationale: The correct answer is D, baked fish and steamed vegetables. These food choices are low in potassium and phosphorus, which is important for clients with chronic kidney disease to manage their condition effectively. Grilled chicken and rice (choice B) may be high in phosphorus, tomato soup with saltine crackers (choice C) is high in sodium, and a peanut butter and jelly sandwich (choice A) contains high levels of potassium, all of which are not ideal choices for individuals with chronic kidney disease.
