Correct Answer: D

Rationale: The correct answer is D. A platelet count of 100,000/mm3 is lower than the normal range, indicating thrombocytopenia, which is concerning in clients receiving chemotherapy. Thrombocytopenia can lead to an increased risk of bleeding and bruising. Choices A, B, and C fall within the normal range and would not be a cause for concern in a client receiving chemotherapy.

Correct Answer: B

Rationale: The correct intervention for a client with pneumonia is to perform chest percussion every 4 hours. Chest percussion helps loosen secretions and improve airway clearance in clients with pneumonia. Placing the client in the supine position can worsen breathing, so it is incorrect. Administering oxygen via nasal cannula is a common intervention for clients with respiratory issues but is not specific to pneumonia. Limiting fluid intake to 1,500 mL/day may not be appropriate as pneumonia can lead to dehydration, so it is not the priority intervention.

Correct Answer: A

Rationale: The correct answer is to assess the patient for injuries. When a patient experiences a fall in the hospital, the immediate concern is to check for any injuries that may require urgent care. Calling for help can be done after assessing the patient to ensure appropriate assistance is provided. Documenting the fall is important for the patient's medical record, but it is not the most immediate action needed. Notifying the healthcare provider can come after the initial assessment to update them on the situation.

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: Educate the patient on the importance of medication. Providing education to the patient is crucial in promoting understanding of the condition and the necessity of medication. By enhancing the patient's knowledge, healthcare providers can empower them to make informed decisions regarding their health. Choice B, respecting the patient's decision, may not be appropriate in this scenario as untreated hypertension can lead to serious complications. Choice C, informing the healthcare provider, is important but should be done after attempting to educate the patient. Choice D, exploring alternative treatment options, may be considered if the patient has concerns or side effects related to the medication, but initially, educating the patient about the importance of medication is key.
