Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C because the SUPPORT study revealed disparities between patients' care preferences and the actual care provided. This is supported by the findings that many patients did not receive treatments aligned with their preferences. Choice A is incorrect because the study actually highlighted communication challenges between patients and healthcare providers. Choice B is incorrect as the study showed that critical care units often do not meet the needs of dying patients and their families. Choice D is incorrect as the study found that pain and suffering of patients at the end of life are not always well controlled in hospitals.

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.

Correct Answer: C

Rationale: The correct answer is C: Damage to the type II pneumocytes, which produce surfactant. Acute respiratory distress syndrome (ARDS) is characterized by damage to the alveolar epithelium, including type II pneumocytes responsible for producing surfactant. Surfactant reduces surface tension in the alveoli, preventing collapse. Damage to type II pneumocytes impairs surfactant production, leading to alveolar collapse and impaired gas exchange. Choices A, B, and D are incorrect because ARDS is not primarily caused by a decrease in white blood cells, damage to the right mainstem bronchus, or decreased capillary permeability.

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: C

Rationale: The correct answer is C because notifying the organ procurement organization (OPO) once the patient has been pronounced brain dead is a requirement to sustain CMS Conditions of Participation. This step ensures that the proper protocols are followed for organ donation. Choice A is incorrect because notifying the OPO of impending death is not a requirement for sustaining CMS Conditions of Participation. Choice B is incorrect because obtaining informed consent for organ donation is not directly related to meeting the requirements of CMS Conditions of Participation. Choice D is incorrect because while evaluating the patient's suitability for organ donation is important, it is not a specific requirement under CMS Conditions of Participation.
