Correct Answer: C

Rationale: The correct answer is C: Client's vaccination history. Before administering a pneumococcal vaccine, the nurse should verify the client's vaccination history to ensure they are due for the vaccine. Verifying the vaccination history helps prevent unnecessary vaccinations and ensures that the client receives the appropriate immunization at the right time. Choices A, B, and D are not directly related to the administration of the pneumococcal vaccine. Checking for allergies to eggs may be important for other vaccines, but it is not specifically relevant to pneumococcal vaccination. The client's current medications and blood pressure are important for general health assessment but are not directly related to verifying the need for a pneumococcal vaccine.

Correct Answer: B

Rationale: The correct answer is B: Eye exams. Hydroxychloroquine can cause retinal damage, making it essential for the nurse to monitor the client's eyes regularly for any changes. Monitoring liver function tests (choice A), blood glucose levels (choice C), or complete blood count (choice D) are not directly associated with the potential side effects of hydroxychloroquine.

Correct Answer: D

Rationale: When assessing a client for signs of depression, healthcare professionals should look for changes in sleep patterns and weight loss. These are common symptoms associated with depression. Increased energy (choice A) is not typically a sign of depression, as individuals with depression often experience fatigue and a lack of energy. Therefore, choices A, B, and C are incorrect, making choice D the correct answer.

Correct Answer: C

Rationale: The correct answer is C: No action is needed at this time. Sedation from opiates commonly decreases as the body adjusts to the medication. It is a positive sign that the sedation has resolved, indicating the client is tolerating the current dosage well. Initiating additional non-pharmacological pain management techniques (Choice A) is unnecessary since the current pain management regimen is effective. Notifying the provider for a dosage adjustment (Choice B) is premature and not indicated when the sedation has resolved. Contacting the provider to request an alternate method of pain management (Choice D) is excessive and not warranted in this situation where the client is no longer sedated and the current pain management plan is effective.

Correct Answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.
