Correct Answer: A

Rationale: The correct way to assess and manage a patient with dehydration is to assess skin turgor and monitor intake/output. Skin turgor assessment helps in evaluating the degree of dehydration, while monitoring intake/output aids in maintaining fluid balance. Encouraging oral fluids only (Choice B) may not be sufficient for moderate to severe dehydration as patients may need intravenous fluids (IV) to rapidly rehydrate. Administering IV fluids immediately (Choice C) is not always the first step unless the patient is severely dehydrated. Checking for electrolyte imbalance and administering fluids (Choice D) is important but comes after assessing skin turgor and intake/output in the management of dehydration.

Correct Answer: B

Rationale: The correct answer is B: 'Keep oxygen tanks upright at all times.' Oxygen tanks should be stored in an upright position to prevent leaks and accidents. Choice A is incorrect as smoking should never be allowed near oxygen due to the risk of fire. Choice C is incorrect as oxygen equipment should be stored in a well-ventilated area, not in a closet. Choice D is incorrect as oxygen tanks must be kept a minimum of 5 to 10 feet away from heat sources to prevent combustion. Therefore, the best practice is to keep oxygen tanks upright to ensure safety.

Correct Answer: A

Rationale: The correct nursing intervention for a patient with a pressure ulcer is to clean the wound and apply a hydrocolloid dressing. This promotes healing by creating a moist environment conducive to the wound healing process. Choice B is incorrect because while nutrition is important for wound healing, a high-protein diet alone is not a specific intervention for a pressure ulcer. Choice C is incorrect as antibiotics are only used if there is an infection present. Choice D is also incorrect as a low-sodium diet and monitoring for fluid retention are more related to conditions like heart failure or kidney disease, not specifically pressure ulcer care.

Correct Answer: B

Rationale: The correct instruction that the nurse should include is to rotate injection sites with each dose. This practice is essential to prevent tissue damage and ensure proper insulin absorption. Option A is incorrect because insulin should not be injected into the muscle, but rather into the subcutaneous tissue. Option C is incorrect as insulin should be stored in the refrigerator to maintain its effectiveness. Option D is incorrect as massaging the injection site after administration can lead to faster absorption and potentially hypoglycemia.

Correct Answer: D

Rationale: After securing the airway, initiating IV fluids is the priority to prevent hypovolemic shock in clients with severe burns. IV fluids help maintain circulating volume and prevent a drop in blood pressure due to fluid loss. Providing pain management, offering emotional support, and preventing infection are important aspects of care but are secondary to ensuring adequate fluid resuscitation in clients with severe burns.
