Correct Answer: C

Rationale: The correct first action for the nurse to take after realizing that the wrong medication has been administered to a client is to monitor vital signs. Monitoring vital signs is crucial as it allows the nurse to promptly assess for any immediate adverse effects that may result from the wrong medication. This immediate assessment is essential for ensuring the client's safety and well-being. Notifying the provider (choice A) and reporting the incident to the nurse manager (choice B) are important steps to take, but they should come after ensuring the client's immediate safety. Filling out an incident report (choice D) is also necessary but should be done after addressing the client's immediate needs.

Correct Answer: C

Rationale: The correct action to reduce the risk of aspiration during enteral feedings is to elevate the head of the bed to 45 degrees. This position helps prevent the reflux of feeding into the lungs. Administering the feeding over 60 minutes (Choice A) does not directly reduce the risk of aspiration. Positioning the client in a supine position (Choice B) increases the risk of aspiration as it promotes reflux. Flushing the feeding tube with water (Choice D) is important for tube patency but does not directly reduce the risk of aspiration.

Correct Answer: D

Rationale: An irregularly shaped mole is a priority finding to report to the provider as it can be indicative of melanoma, a type of skin cancer. Melanoma is a serious condition that requires prompt evaluation and treatment. Raised nevus, macule, and vesicle are common skin findings that are typically benign and may not require immediate attention. Therefore, the irregularly shaped mole stands out as the priority due to its association with potential malignancy.

Correct Answer: A

Rationale: The correct answer is A. Weight gain can indicate myxedema, which is a symptom commonly seen in hypothyroidism. Exophthalmos (choice B) is actually a characteristic finding of hyperthyroidism, not hypothyroidism. Tachycardia (choice C) and heat intolerance (choice D) are also more indicative of hyperthyroidism rather than hypothyroidism.

Correct Answer: B

Rationale: The correct action the nurse should take when caring for a client receiving brachytherapy is to limit the client's visitors to 30 minutes per day. This is crucial to reduce exposure to radiation and maintain safety during the brachytherapy procedure. Cleansing equipment before removal from the client's room may be important for infection control but is not directly related to brachytherapy procedures. Discarding the client's linens in a double bag and discarding the radioactive source in a biohazard bag are incorrect choices as they do not specifically address the safety measures needed during brachytherapy for prostate cancer.
