Correct Answer: B

Rationale: In this scenario, the patient is presenting with acute exacerbation of chronic heart failure (CHF) complicated by pulmonary edema and respiratory distress. The priority intervention for managing this exacerbation is to initiate positive pressure ventilation for respiratory support. Positive pressure ventilation, such as non-invasive positive pressure ventilation (NIPPV) or invasive mechanical ventilation, can help improve oxygenation and decrease the work of breathing for the patient. By providing adequate respiratory support, ventilation can reduce the negative effects of pulmonary edema and respiratory distress due to CHF exacerbation. Administering intravenous loop diuretics (Choice A) might be necessary to address fluid overload, but it is not the initial priority as ensuring adequate ventilation is crucial. Emergent pericardiocentesis (Choice C) is not indicated in this scenario as there is no mention of cardiac tamponade. Inotropic medications (Choice D) may be considered in managing acute exacerbation of CHF but

Correct Answer: B

Rationale: Atorvastatin is a medication commonly used for lipid-lowering therapy to reduce cholesterol levels and decrease the risk of cardiovascular events. However, one of the potential side effects of statin medications such as atorvastatin is liver injury. Therefore, monitoring liver function tests, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, is crucial during atorvastatin therapy.

Correct Answer: C

Rationale: In situations where a patient's family member is expressing anxiety about their loved one's condition, it is important for the nurse to provide clear and accurate information about the patient's status. By explaining the nature of the injury and reassuring the wife that her husband's condition is stable, the nurse can help alleviate her anxiety and address her concerns in a meaningful way. This intervention focuses on open communication and providing emotional support, which are crucial in helping the family member cope with the situation. It is essential to establish trust and create a supportive environment for the family member during this stressful time.

Correct Answer: B

Rationale: A "full understanding" in research should be understood by the nurse researcher as explaining the study including risks and ben . When conducting research involving participants, it is crucial for nurse researchers to provide all necessary information about the study, including potential risks and benefits, in a clear and understandable manner. This ensures that participants are well-informed and can make informed decisions about their participation. By explaining the study thoroughly, nurse researchers uphold ethical principles such as informed consent and respect for participants' autonomy. It also helps in building trust between the researcher and participants, ultimately leading to more reliable and ethical research outcomes.

Correct Answer: A

Rationale: The clinical presentation described is highly suggestive of acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. The red eye, steamy cornea (due to corneal edema), and mid-dilated, non-reactive pupil (from the unopposed force of the dilator muscle) are classic findings in acute angle-closure glaucoma. The increase in intraocular pressure compromises blood flow to the eye, leading to symptoms of blurred vision and possible visual loss. Immediate management usually involves lowering intraocular pressure with medications or surgical intervention to prevent vision loss. Central retinal artery occlusion, optic neuritis, and corneal ulcer typically present with different clinical features and are not consistent with the described presentation.
