Correct Answer: A

Rationale: The correct answer is A: Narrowed arterial lumen. Arterial bruits are abnormal sounds caused by turbulent blood flow through narrowed or occluded arteries. This turbulent flow creates a blowing sound, which is heard as an arterial bruit. Distended jugular veins (choice B) are typically associated with venous issues, not arterial abnormalities. Impaired ventricular contraction (choice C) and asynchronous closure of the aortic and pulmonic valve (choice D) are not directly related to the audible vascular sound described in the scenario.

Correct Answer: A

Rationale: The correct answer is A. Using non-acetone nail polish remover is crucial for clients on supplemental oxygen as acetone is flammable and poses a safety risk. Acetone can react with oxygen, increasing the fire hazard. Choices B, C, and D are incorrect. Electric razors can generate sparks, which are dangerous near oxygen due to the risk of ignition. While cleaning oxygen equipment is important, the type of nail polish remover used is more critical for immediate safety. Wool blankets can create static electricity, increasing the risk of fire around oxygen due to its flammability.

Correct Answer: D

Rationale: Hypotension is a critical finding that should be reported immediately in a client with acute pancreatitis as it may indicate severe complications such as hemorrhage or shock. While elevated serum lipase level, severe abdominal pain, and nausea/vomiting are common manifestations of acute pancreatitis, hypotension is a more urgent sign requiring immediate attention to prevent further deterioration. Hypotension can be a sign of significant fluid loss, hemorrhage, or sepsis, which are potentially life-threatening conditions that need prompt intervention. Elevated serum lipase levels, severe abdominal pain, and nausea/vomiting are important in the assessment of pancreatitis but do not indicate the same level of immediate danger as hypotension does.

Correct Answer: A

Rationale: When a patient reports an inability to clear nasal passages, the appropriate action for the nurse to take is to use gentle suction to prevent tissue damage. Suctioning helps remove excess mucus or secretions without causing harm to the nasal tissues. Instructing the patient to blow their nose forcefully (Choice B) may exacerbate the issue and cause discomfort or injury. Placing a dry washcloth under the nose (Choice C) is not an effective intervention for clearing nasal passages. Inserting a cotton-tipped applicator into the back of the nose (Choice D) is not recommended as it can be invasive and may cause injury or discomfort to the patient.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to ask the client if she plans to harm herself. This is crucial to assess the client's risk of self-harm or suicide. Providing immediate safety and appropriate interventions is the priority when a client expresses such thoughts. Requesting additional support from the family (Choice A) may be helpful but does not address the immediate safety concern. Informing the client that feeling this way is normal (Choice C) may invalidate her feelings and does not address the safety risk. Suggesting counseling (Choice D) may be beneficial in the long term but is not the immediate priority when assessing for self-harm or suicide risk.
