Nursing Elites

1. The client is being taught how to use a peak flow meter. The nurse explains that this device should be used to:

• A. Determine oxygen saturation
• B. Measure forced expiratory volume
• C. Monitor the atmosphere for the presence of allergens
• D. Provide metered doses for inhaled bronchodilator

Correct answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.

2. The nurse is teaching the parents of a child who has head lice (pediculosis capitis). Which information will the nurse include in the teaching session?

• A. Treatment involves using regular shampoo.
• B. Products containing lindane are not recommended.
• C. Head lice may spread to furniture and other people.
• D. Manual removal is essential in treatment.

Correct answer: C

Rationale: The correct answer is C. Head lice are highly contagious and can spread to furniture and other people if not treated promptly. Informing the parents about the potential spread of head lice emphasizes the importance of thorough treatment and prevention measures. Choice A is incorrect as regular shampoo is not typically effective in treating head lice. Choice B is incorrect as products containing lindane are not recommended due to safety concerns. Choice D is incorrect as manual removal, though labor-intensive, is a crucial step in effectively treating head lice infestations, but it is not the most pertinent information to include in the teaching session.

3. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?

• A. Blood glucose level
• B. Prothrombin time (PT) and INR
• C. Serum potassium level
• D. Serum creatinine level

Correct answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

4. A client with a history of falls is under the care of a nurse. Which of the following actions should be the nurse’s priority?

• A. Complete a fall-risk assessment.
• B. Educate the client and family about fall risks.
• C. Eliminate safety hazards from the client’s environment.
• D. Ensure the client uses assistive aids in their possession.

Correct answer: C

Rationale: The nurse's priority should be to eliminate safety hazards from the client's environment as it directly reduces the risk of falls. Addressing environmental hazards is an immediate and crucial step in preventing falls. While completing a fall-risk assessment is important to understand the client's risk factors, educating the client and family about fall risks is essential for prevention, and ensuring the use of assistive aids is crucial for safety, eliminating safety hazards takes precedence as it directly mitigates the risk of falls.

5. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Monitor serum calcium levels.
• B. Monitor serum potassium levels.
• C. Monitor serum sodium levels.
• D. Monitor serum magnesium levels.

Correct answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
