Correct Answer: A

Rationale: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.

Correct Answer: A

Rationale: The correct answer is A: 'Heart disease and stroke.' Untreated hypertension can lead to various complications, including heart disease and stroke. These are common outcomes of long-term high blood pressure. Choice B, 'Kidney failure and vision loss,' is incorrect as kidney failure and vision loss are more commonly associated with diabetic complications rather than untreated hypertension. Choice C, 'Pulmonary embolism and arrhythmias,' while serious, are not among the primary complications of untreated hypertension. Choice D, 'Blood clots and gastrointestinal bleeding,' are not typical complications of untreated hypertension but can occur due to other conditions such as blood clotting disorders or gastrointestinal diseases.

Correct Answer: B

Rationale: The correct answer is B: "Use a bed exit alarm system." For a client with dementia at risk for falls, a bed exit alarm system is beneficial as it alerts staff when the client is trying to get up, helping to reduce fall risks. Choice A, maintaining the client's bed in the lowest position, may not prevent falls as effectively as an alarm system. Choice C, assisting the client with ambulation every hour, may not be feasible and could disrupt the client's rest. Choice D, raising all 4 side rails for safety, can lead to restraint issues and is not recommended as a routine fall prevention measure.

Correct Answer: C

Rationale: The correct answer is C: Persistent cough. Enalapril is known to cause a persistent dry cough as a side effect. This adverse reaction is due to the accumulation of bradykinin in the lungs, leading to irritation and cough. The nurse should report this symptom to the provider for further evaluation and possible medication adjustment. Choices A, B, and D are not directly associated with enalapril use. While a blood pressure of 150/80 mm Hg is elevated and should be monitored, it is not a direct side effect of enalapril. Swelling in the legs and a heart rate of 72 beats per minute are also not typically related to enalapril use and should be assessed but are not the priority findings to report in this scenario.

Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the priority action for the nurse is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and removing the IV can help prevent further complications. Applying a warm compress may provide symptomatic relief but does not address the root cause. Monitoring for infection is important, but immediate action to remove the source of inflammation is crucial. Administering an anti-inflammatory medication is not the first-line intervention for phlebitis; removal of the IV is necessary.
