Correct Answer: A

Rationale: Hypoglycemia typically presents with sweating and trembling, while hyperglycemia is characterized by frequent urination and thirst. Therefore, the correct key differences between hypoglycemia and hyperglycemia are that hypoglycemia includes symptoms like sweating and trembling, while hyperglycemia involves symptoms such as frequent urination and thirst. Choices B, C, and D are incorrect because they do not accurately represent the characteristic symptoms of hypoglycemia and hyperglycemia, as stated in the question.

Correct Answer: A

Rationale: The correct answer is A: Ensure the injection produces a wheal on the skin. A wheal indicates that the PPD has been administered correctly, allowing for the proper interpretation of results. Administering the injection in the client's thigh (choice B) is not the recommended site for PPD administration; it should be administered intradermally. Using an 18-gauge needle (choice C) is unnecessary and not the standard practice for PPD administration as a smaller gauge needle is preferred for intradermal injections. Massaging the site after injection (choice D) can lead to inaccurate results by dispersing the solution, so it is important to avoid touching the site after the injection to prevent altering the test results.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with neutropenia include monitoring for signs of infection and administering antibiotics. Neutropenia is characterized by a low neutrophil count, which increases the risk of infections. Monitoring for signs of infection allows for early detection and prompt treatment, while administering antibiotics helps prevent or treat any infections that may occur. Isolating the patient and providing a low-microbial diet (Choice B) are not necessary unless the patient develops an active infection. Monitoring vital signs and avoiding unnecessary invasive procedures (Choice C) are important but do not specifically address the increased infection risk in neutropenic patients. Encouraging the patient to engage in social activities (Choice D) is not appropriate for a neutropenic patient due to the risk of exposure to infectious agents.

Correct Answer: A

Rationale: A below-the-knee amputation requires immediate attention due to the risk of hemorrhage and shock, making it the highest priority. This type of injury can lead to significant blood loss and impaired perfusion, which can be life-threatening if not addressed promptly. While a 10 cm laceration, a fractured tibia, and a 95% full-thickness body burn are serious injuries requiring urgent care, they do not pose the same immediate threat to life as a below-the-knee amputation. The laceration may require suturing to control bleeding and prevent infection, the fractured tibia needs stabilization to prevent further damage and pain, and the burn necessitates immediate management to prevent complications, but they are not as acutely life-threatening as the amputation.

Correct Answer: A

Rationale: The correct answer is A, 'Beneficence.' Beneficence is the ethical principle that involves taking positive actions to help others. Choice B, 'Justice,' pertains to fairness and equity in treatment, not specifically positive actions. Choice C, 'Autonomy,' relates to respecting individuals' rights to make their own decisions, not necessarily taking actions to help others. Choice D, 'Non-maleficence,' focuses on the obligation to avoid causing harm rather than actively helping others.
