Correct Answer: B

Rationale: The correct answer is B: Do not use underarm deodorant. This instruction is important because deodorant can interfere with the imaging results by causing artifacts on the mammogram images. Using deodorant can lead to false positives or false negatives, affecting the accuracy of the test results. Choice A is incorrect because using underarm deodorant can negatively impact the mammogram results. Choice C is incorrect as there is no need for the client to fast before a mammogram. Choice D is also incorrect as having a friend drive you home is not a necessary instruction for a mammography appointment.

Correct Answer: A

Rationale: The correct answer is A: Chest pain. A symptom is a subjective indication of a condition experienced by the patient. Chest pain is a subjective sensation that a patient reports, making it a symptom. Clammy skin, serum potassium level, and temperature are all objective signs or measurements, not subjective experiences reported by the patient. Symptoms are what the patient feels or experiences, while signs are objective findings that can be measured or observed by healthcare providers.

Correct Answer: B

Rationale: The correct answer is B: ondansetron (Zofran). Ondansetron is a selective serotonin receptor antagonist that effectively targets the serotonin receptors in the chemoreceptor trigger zone to relieve nausea and vomiting. It is commonly used in chemotherapy-induced nausea and vomiting. A: Metoclopramide is a dopamine receptor antagonist and primarily used for gastrointestinal motility disorders, not specifically for nausea relief. C: Hydroxyzine is an antihistamine with sedative properties, primarily used for anxiety and itching, not specifically for nausea relief. D: Prochlorperazine is a dopamine receptor antagonist primarily used for treating psychotic disorders, not specifically for nausea relief. In summary, ondansetron is the correct choice as it targets serotonin receptors specifically for relieving nausea and vomiting, whereas the other options focus on different mechanisms of action.

Correct Answer: B

Rationale: The correct answer is B. When a client is moving towards illness and premature death, signs and symptoms typically start to manifest. These can include physical changes, abnormal lab results, or new onset of health issues. This serves as a direct indication of the client's deteriorating health status. Choices A, C, and D are incorrect because stopping wellness-promoting activities (A) could simply be due to lack of motivation, starting to exercise (C) may not necessarily indicate illness progression, and verbalizing anxiety over medication costs (D) is not a direct indicator of impending illness and premature death.

Correct Answer: C

Rationale: The correct answer is C because asking open-ended questions helps the patient express their feelings without feeling pressured. This approach allows the patient to share at their own pace and comfort level. Choice A may make the patient feel uncomfortable or pressured. Choice B may not address the underlying issue of the patient's avoidance of eye contact. Choice D is more direct and may not be effective if the patient is not ready to discuss their emotions. Ultimately, using open-ended questions promotes a safe and supportive environment for the patient to open up willingly.
