Correct Answer: A

Rationale: The correct answer is A. Pain radiating to the left arm is a classic symptom of myocardial infarction, commonly known as a heart attack. This occurs due to the referred pain pathways shared by the heart and the left arm. Choices B, C, and D are incorrect. Pain relieved by rest (choice B) is more indicative of musculoskeletal pain rather than cardiac-related pain. Pain worsening with deep breathing (choice C) is often seen in conditions like pleurisy or pulmonary embolism, not myocardial infarction. Pain relieved by antacids (choice D) suggests gastrointestinal issues like heartburn or acid reflux, not cardiac-related pain.

Correct Answer: A

Rationale: The correct question the nurse should ask the client who is 38 weeks pregnant with herpes simplex virus is 'Do you have any active lesions?' This is crucial because active herpes lesions may necessitate a cesarean delivery to prevent neonatal infection. Choice B, 'Have your membranes ruptured?' is related to assessing for the rupture of membranes, not specific to the client's herpes infection. Choice C, 'How far apart are your contractions?' is related to monitoring labor progress. Choice D, 'Are you positive for beta strep?' is related to group B streptococcus screening, which is important but not the priority in this scenario.

Correct Answer: B

Rationale: The correct answer is B, Hydromorphone. Hydromorphone is an opioid analgesic commonly used to manage severe pain effectively. In this case, the client's stable respiratory rate of 14/min indicates that it is safe to administer an opioid for pain relief. Promethazine (choice A) is an antiemetic and antihistamine, not the first choice for severe pain management. Ketorolac (choice C) is a nonsteroidal anti-inflammatory drug (NSAID) that may not be potent enough for severe pain relief associated with osteoporosis. Amitriptyline (choice D) is a tricyclic antidepressant, not typically used as a first-line medication for severe pain.

Correct Answer: B

Rationale: The correct instruction the nurse should provide to a client prescribed ferrous sulfate is to take it with fluids other than coffee or tea. Coffee and tea can inhibit iron absorption. Therefore, choices A, C, and D are incorrect. Avoiding strawberries, citrus fruits, and melon is not necessary for improving absorption of ferrous sulfate, taking it on a full stomach is not recommended, and doubling the dose if a dose is missed can lead to an overdose.

Correct Answer: A

Rationale: Assessing allergies before administering a new medication is crucial as it helps prevent potentially life-threatening allergic reactions like anaphylaxis. While monitoring vital signs and informing the client of side effects are important nursing actions, assessing allergies takes precedence to ensure the client's safety. Informed consent is necessary for the treatment process, but assessing allergies is the priority before administering any new medication.
