Correct Answer: A

Rationale: The correct answer is A because a second nurse should verify and enter the prescription into the client's medical record to ensure accuracy. This step is crucial to prevent errors in transcription and administration. Choice B is incorrect as having another nurse listen to the phone call does not ensure accurate transcription. Choice C is incorrect because the provider clarifying the prescription upon signing the health record does not replace the need for proper documentation. Choice D is incorrect because the 'read back' process is essential for all telephone prescriptions to confirm accuracy and prevent errors in transcription or administration.

Correct Answer: A

Rationale: When a client is expressing anger about a diagnosis, it is essential for the nurse to validate the client's feelings. Choice A is correct because reassuring the client that anger is an expected response to grief acknowledges the client's emotions and encourages expression, fostering a therapeutic relationship. This validation helps the client feel understood and supported during a challenging time. Choice B is incorrect as ignoring the client's anger can lead to feelings of neglect and hinder effective communication, which is crucial for providing holistic care. Choice C is inappropriate because telling the client that anger is not helpful dismisses the client's emotions and can further escalate the situation, potentially damaging the nurse-client relationship. Choice D is not the best option as it does not involve acknowledging the client's feelings or providing support and validation, which are vital in promoting emotional well-being and trust between the client and the nurse.

Correct Answer: A

Rationale: Bruises on the arms in various stages of healing should be identified as a potential indication of abuse in an older adult. These bruises may suggest physical harm or neglect, which are concerning signs of abuse. Recent weight gain (Choice B) is not typically associated with abuse and can have various causes, such as dietary changes or health conditions. Complaints of joint pain (Choice C) are more likely related to musculoskeletal issues rather than abuse. Frequent visits to different providers (Choice D) could indicate seeking multiple opinions or healthcare needs and do not necessarily point to abuse.

Correct Answer: A

Rationale: When encountering an unfamiliar medication, the safest action for a nurse is to consult the medication reference book available on the unit. This resource provides accurate and detailed information about medications, including indications, dosages, side effects, and nursing considerations. Administering a medication without understanding it (choice B) can lead to medication errors and harm to the client. Asking a colleague for information (choice C) may not always provide accurate or up-to-date information. Contacting the provider (choice D) should be reserved for situations where immediate clarification is needed, but consulting the reference book is the initial step to gain knowledge and ensure safe medication administration.

Correct Answer: D

Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.
