What are the risk factors for the development of pressure ulcers, and how can they be prevented?

Correct Answer: A

Rationale: The correct answer is A: Immobility and poor nutrition are significant risk factors for pressure ulcers. Immobility leads to prolonged pressure on certain body areas, increasing the risk of tissue damage. Poor nutrition can impair skin integrity and the body's ability to heal. Prevention strategies include frequent turning and repositioning to relieve pressure points. Choice B is incorrect because increased mobility actually reduces the risk of pressure ulcers. Choice C is incorrect as excess moisture can contribute to skin breakdown, but it is not a primary risk factor. Choice D is incorrect as frequent turning and repositioning are part of the prevention measures, not risk factors.

Correct Answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.

Correct Answer: C

Rationale: The correct answer is C because avoiding solid foods after bariatric surgery is crucial to prevent complications and promote healing. Choice A is incorrect as carbonated beverages can cause discomfort and should be avoided. Choice B is incorrect as large meals are not suitable after bariatric surgery. Choice D is incorrect as taking small sips of liquids is encouraged to prevent dehydration and promote recovery.

Correct Answer: C

Rationale: The correct instruction for the client with left-leg weakness using a cane is to maintain two points of support on the floor. This ensures stability and balance while walking. Choice A is incorrect because the cane should be used on the strong side of the body to provide additional support. Choice B is incorrect as the cane and the weak leg should move together for support. Choice D is incorrect as advancing the cane too far with each step may compromise balance and stability.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators and monitor oxygen levels. Asthma management involves using bronchodilators to help open the airways and improve breathing. Monitoring oxygen levels is essential to ensure the patient is getting enough oxygen. Choice B, encouraging deep breathing exercises, can be helpful for some respiratory conditions but is not a key intervention for managing an acute asthma attack. Choice C, providing corticosteroids and monitoring for respiratory distress, is important for long-term asthma management and severe exacerbations but is not the immediate key intervention during an acute attack. Choice D, providing antihistamines and monitoring blood pressure, is not typically indicated for asthma management as asthma is primarily an airway disease, not a histamine-mediated condition.

Correct Answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

Correct Answer: A

Rationale: The correct answer is A. A neurological assessment includes evaluating the level of consciousness and motor function as they are key components in assessing neurological function. Choices B, C, and D are incorrect as headache, nausea, reflexes, pupil size, tremors, and confusion may be part of a neurological assessment but are not the key components that are fundamental for a comprehensive assessment.

Correct Answer: B

Rationale: The correct answer is B. Ethical dilemmas involve conflicting values or feelings. In this situation, the family is conflicted about tube feeding for their terminally ill father, which presents a moral and ethical challenge. Choices A, C, and D do not represent ethical dilemmas. Choice A involves a nurse's impairment, which is a different issue. Choice C involves a nurse's observation of a colleague's threat, which is a patient safety concern. Choice D involves a client's hesitation in naming a spouse as power of attorney, which is a legal and decision-making issue, not necessarily an ethical dilemma.

Correct Answer: A

Rationale: Corrected DVT management involves administering anticoagulants to prevent clot growth and monitoring for signs of bleeding. Elevating the limb and administering pain relief (Choice B) may help alleviate symptoms but do not address the underlying issue of preventing clot progression. Restricting mobility and applying warm compress (Choice C) could potentially dislodge the clot and worsen the condition. Administering IV fluids and providing bed rest (Choice D) are not primary interventions for managing DVT.
