Critical Care Nursing NCLEX Questions

Correct Answer: B

Rationale: The correct answer is B because certification validates nurses' expert knowledge and practice. This is important as it ensures that nurses have the necessary skills and competence to provide high-quality care in critical care settings. Certification is voluntary and not mandated by government regulations (Choice C). It goes beyond demonstrating basic knowledge (Choice D) by confirming specialized expertise. While certification may garner positive publicity (Choice A), the primary benefit is the validation of advanced skills and knowledge.

Correct Answer: C

Rationale: The correct answer is C: Measure the patient�s urinary output every hour. This is crucial because monitoring urinary output is essential in assessing the patient�s renal function and the effectiveness of the intra-aortic balloon pump in improving cardiac output. Hourly measurement helps in early detection of any changes that may indicate complications. A: Positioning the patient supine at all times is not necessary and can lead to complications. B: Avoiding the use of anticoagulant medications is not appropriate as they are often necessary to prevent clot formation around the balloon pump. D: Providing a massive range of motion for all extremities is not recommended for a patient with an intra-aortic balloon pump as it can dislodge the device or cause harm.

Correct Answer: B

Rationale: The correct answer is B: Assist with the intubation of the patient. In this scenario, the patient is unconscious and has ingested a potentially harmful substance. Intubation is the first priority to maintain the patient's airway and ensure adequate oxygenation. This step is crucial in preventing aspiration of gastric contents and securing the patient's respiratory status. Inserting a large-bore orogastric tube (choice A) is not the priority as airway management takes precedence. Preparing a syringe with saline (choice C) is unnecessary at this stage. Giving the first dose of activated charcoal (choice D) should only be done after securing the airway to prevent aspiration.

Correct Answer: A

Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function because in healthy kidneys, proteins are retained in the blood and not filtered into the urine. If protein is found in the filtrate, it suggests damage to the glomerular filtration barrier. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not indicative of renal dysfunction. Sodium is freely filtered and reabsorbed, creatinine is a waste product of muscle metabolism excreted by the kidneys, and a small number of red blood cells may be filtered due to their small size. Therefore, protein in the glomerular filtrate is the most specific indicator of renal dysfunction.

Correct Answer: C

Rationale: The correct answer is C: Procedures performed in the operating room are associated with fewer complications. This is because performing a tracheostomy in the operating room allows for better control of the environment, equipment, and expertise of the surgical team. In this setting, the risk of complications such as bleeding, infection, and injury to surrounding structures is minimized. Choices A, B, and D are incorrect: A: Patient outcomes are better if the tracheostomy is done within a week of intubation - This statement is not universally true and depends on individual patient factors. Timing of tracheostomy should be based on the patient's clinical condition and not a set timeline. B: Percutaneous tracheostomy can be done safely at the bedside by the respiratory therapist - While percutaneous tracheostomy can be performed at the bedside, it is typically done by a trained physician or surgeon due to the potential risks and complications involved. D: The greatest risk after a per
