Critical Care Nursing Practice Questions Questions

Question 1 of 5

A male client who has been taking propranolol (Inderal) for 18 months tells the nurse that the healthcare provider discontinued the medication because his blood pressure has been normal for the past three months. Which instruction should the nurse provide?

Correct Answer: D

Rationale: The correct answer is D: Ask the healthcare provider about tapering the drug dose over the next week. This answer is correct because propranolol is a beta-blocker, and abrupt discontinuation can lead to rebound hypertension, angina, or even myocardial infarction due to the sudden withdrawal of the medication. Tapering the drug dose over time allows the body to adjust gradually and reduces the risk of these adverse effects. Choice A is incorrect because obtaining another antihypertensive prescription is not necessary if the client's blood pressure has been normal for the past three months. Choice B is incorrect because abruptly stopping the medication without tapering can lead to withdrawal symptoms. Choice C is incorrect because simply reporting uncomfortable symptoms without taking appropriate action (tapering the drug dose) is not addressing the potential risks associated with abrupt discontinuation of propranolol.

Question 2 of 5

The patient is in need of immediate hemodialysis, but has no vascular access. The nurse prepares the patient for insertion of

Correct Answer: A

Rationale: The correct answer is A: a percutaneous catheter at the bedside. This is the most appropriate option for immediate hemodialysis when the patient has no vascular access. A percutaneous catheter can be quickly inserted at the bedside, allowing for immediate initiation of hemodialysis. Choice B, a percutaneous tunneled catheter, involves a more complex insertion process and is not typically done at the bedside. Choices C and D, arteriovenous fistula and arteriovenous graft, require advanced planning and surgical procedures, making them unsuitable for immediate hemodialysis in this scenario.

Question 3 of 5

A nurse wishes to practice using the Synergy Model developed by the American Association of Critical-Care Nurses (AACN). What nursing behavior best supports use of this model?

Correct Answer: B

Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.

Question 4 of 5

Acute kidney injury from postrenal etiology is caused by

Correct Answer: A

Rationale: The correct answer is A because postrenal acute kidney injury is caused by obstruction of urine flow, leading to pressure build-up in the kidneys and subsequent damage. Obstructions can be due to conditions such as kidney stones, tumors, or enlarged prostate. Choices B, C, and D are incorrect as they relate to pre-renal and intrinsic renal causes of acute kidney injury, not specifically postrenal obstruction. B refers to decreased blood flow to the kidneys, C to low volume or poor heart function affecting kidney perfusion, and D to direct damage to kidney tissue, which do not characterize postrenal etiology.

Question 5 of 5

A 19-year-old is brought to the emergency department (ED) with multiple lacerations and tissue avulsion of the left hand. When asked about tetanus immunization, the patient denies having any previous vaccinations. The nurse will anticipate giving:

Correct Answer: D

Rationale: The correct answer is D because the patient has a high-risk wound (tissue avulsion) and no documented prior tetanus vaccination. TIG provides immediate passive immunity to tetanus, while Tdap stimulates active immunity. TIG covers immediate needs, while Tdap ensures long-term immunity. Choice A (TIG only) does not provide long-term immunity. Choice B (TIG and Td) does not include pertussis coverage, which Tdap (Choice D) does. Choice C (Tdap only) does not cover immediate needs as TIG does.
