Correct Answer: A

Rationale: The correct answer is A because protocols are indeed guidelines that assist clinicians in decision-making and choosing interventions for specific health care problems. This definition accurately reflects the purpose and function of protocols in nursing practice. Option B is incorrect as it describes protocols as policies related to nurses' duties and standards of care, which is more aligned with job descriptions and policies rather than protocols. Option C is incorrect as it relates protocols to a code of ethics, which is a separate concept that guides ethical decision-making and behavior in nursing practice. Option D is incorrect as it inaccurately describes protocols as prescriptive order forms, which are actually separate from protocols and are used for medication administration and treatment orders.

Correct Answer: A

Rationale: The correct answer is A: Monthly testicular self-examination. This is the best way to detect testicular cancer early because it allows individuals to become familiar with the normal size, shape, and texture of their testicles, making it easier to notice any changes or abnormalities. Self-examination is cost-effective, convenient, and can be done regularly to monitor for any signs of cancer. Annual physician examination (B) may not be frequent enough for early detection. Yearly digital rectal examination (C) is not relevant for detecting testicular cancer. Annual ultrasonography (D) is not recommended as a routine screening tool for testicular cancer.

Correct Answer: B

Rationale: The correct answer is B because performing Valsalva maneuver can lead to a sudden drop in blood pressure, causing the client to lose consciousness. This occurs due to the increased intra-abdominal pressure leading to decreased venous return to the heart. Choices A, C, and D are incorrect as they do not accurately reflect the consequences of Valsalva maneuver. Option A stating that the client's blood pressure will decrease momentarily is incorrect as it actually increases initially. Option C suggesting that the client may suffer from a myocardial infarction is incorrect as Valsalva maneuver does not directly cause heart attacks. Option D implying that the client's blood pressure will increase momentarily is also incorrect as the immediate effect is a rise followed by a significant drop.

Correct Answer: A

Rationale: The correct answer is A: Antiemetic. Chemotherapy commonly causes nausea and vomiting as adverse effects. Antiemetics are medications specifically designed to prevent or alleviate nausea and vomiting. Administering an antiemetic helps manage these side effects and improve the patient's quality of life during chemotherapy. Antibiotics (B) are used to treat bacterial infections, not chemotherapy side effects. Antimetabolites (C) are a type of chemotherapy drug, not used to combat its side effects. Anticoagulants (D) are used to prevent blood clots and are not indicated for managing chemotherapy side effects like nausea and vomiting.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. Safety first: Patient safety is the top priority in healthcare. Vital signs provide crucial information about the patient's condition. 2. Accountability: The nurse is responsible for ensuring accurate vital sign documentation. Asking the NAP to record vital signs before medication administration ensures accountability. 3. Communication: Clear communication between healthcare team members is essential to provide quality care. Asking the NAP to record vital signs promotes effective communication. Summary of Incorrect Choices: A (abnormal vital signs): Administering medications without knowing the patient's vital signs, especially if abnormal, can be dangerous and potentially harmful. B (review upon return): Delaying vital sign assessment until later can lead to missed opportunities for timely intervention if the patient's condition changes. D (omit vital signs): Neglecting vital signs based on assumption risks overlooking potential issues that could impact patient care and outcomes.
