What instructions should the nurse give to a client who will undergo mammography?

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: 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: C

Rationale: Step 1: Nutrition is important for healing and energy. Step 2: Elimination is crucial for bowel and bladder function. Step 3: Comfort ensures the client's well-being. Step 4: Safety prevents complications. Step 5: ROM exercises can prevent muscle atrophy. Step 6: Transportation and isotonic exercises are not immediate priorities.

Correct Answer: D

Rationale: The correct answer is D: sodium chloride. Intestinal suctioning in a client with an ileus leads to loss of fluids rich in sodium chloride. This loss can result in electrolyte imbalances and dehydration. Calcium (A), magnesium (B), and potassium (C) are not typically lost in significant amounts through intestinal suctioning in the context of an ileus. Therefore, sodium chloride is the most likely electrolyte to be lost in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Use a bath blanket for warmth and privacy. This is important when making an occupied bed to ensure the comfort and dignity of the patient. The bath blanket provides warmth and privacy during the bed-making process, maintaining the patient's comfort and respecting their privacy. Keeping the bed in a low position (choice A) is important for safety but not directly related to the patient's comfort during bed-making. Constantly raising side rails (choice C) is unnecessary and may cause discomfort to the patient. Moving back and forth between sides (choice D) is not essential for making an occupied bed and may disrupt the process.
