Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries. A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism. B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism. D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.

Correct Answer: C

Rationale: The correct answer is C: Notify the health care provider and postpone the transfer. The new onset confusion in an elderly patient in the ICU can be a sign of delirium, which is a serious condition that requires prompt evaluation and management. By notifying the healthcare provider, they can assess the patient's condition, order appropriate tests, and adjust the treatment plan as needed. Postponing the transfer allows for further observation and intervention to address the underlying cause of the confusion. Choice A (Give PRN lorazepam and cancel the transfer) is incorrect because administering lorazepam may worsen the confusion in an elderly patient and should not be done without proper evaluation. Choice B (Inform the receiving nurse and then transfer the patient) is incorrect because transferring the patient without addressing the new onset confusion can lead to potential complications and delay in appropriate management. Choice D (Obtain an order for restraints as needed and transfer the patient) is incorrect because using restraints should only be considered as a

Correct Answer: C

Rationale: The correct answer is C: Ptosis on the left eyelid. Ptosis refers to drooping of the eyelid, which is a common condition in older adults. In this scenario, the nurse should document the finding as ptosis on the left eyelid because the client's left upper eyelid is drooping, covering more of the iris than the right eyelid. Explanation: Nystagmus (A) is an involuntary eye movement, not related to eyelid drooping. Exophthalmos (B) is the protrusion of the eyeball and not relevant to this scenario. Astigmatism (D) refers to a refractive error of the eye and does not cause eyelid drooping. Therefore, the correct choice is C as it accurately describes the client's condition.

Correct Answer: A

Rationale: The correct answer is A: The FACES scale. This scale uses facial expressions to assess pain, making it suitable for a patient who is unable to verbalize. The nurse can show the patient a series of faces depicting varying levels of pain and ask them to point to the one that best represents their pain level. This method is non-verbal and easy for patients to understand. The other choices are incorrect: B: The Pain Intensity Scale requires the patient to rate their pain on a numerical scale, which may be difficult for a non-verbal patient. C: The PQRST method is a mnemonic for assessing pain characteristics (provocation, quality, region, severity, timing), but it requires patient communication. D: The Visual Analogue Scale involves marking a point on a line to indicate pain intensity, which is not suitable for a non-verbal patient.

Correct Answer: C

Rationale: The correct answer is C because guided imagery involves using the patient's imagination to focus on pleasant sensory experiences. This helps distract the patient from the current situation and reduces anxiety. By remembering tactile sensations of a pleasant experience, the patient can create a calming mental image. Choice A is incorrect because guided imagery does not require an external focus point like a picture. Choice B is incorrect because the technique does not involve staring at a focus point but rather focusing on mental images. Choice D is incorrect because while relaxation is beneficial, guided imagery specifically focuses on visualization of positive experiences to reduce anxiety.
