Nursing Elites

1. The patient is taking low-dose erythromycin prophylactically and will start cefaclor for treating an acute infection. The nurse should discuss this with the provider because taking both medications simultaneously can cause which effect?

• A. Decreased effectiveness of cefaclor.
• B. Increased effectiveness of cefaclor.
• C. Decreased effectiveness of erythromycin.
• D. Increased effectiveness of erythromycin.

Correct answer: A

Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.

2. An overweight client taking warfarin (Coumadin) has dry skin due to decreased arterial blood flow. What should the nurse instruct the client to do? Select all that apply.

• A. Apply lanolin or petroleum jelly to intact skin.
• B. Follow a reduced-calorie, reduced-fat diet.
• C. Inspect the involved areas daily for new ulcerations.
• D. Instruct the client to limit activities of daily living (ADLs).

Correct answer: A

Rationale: To address dry skin and prevent chronic ulcers and infections in an overweight client on warfarin with decreased arterial blood flow, the nurse should instruct the client to apply lanolin or petroleum jelly to intact skin. This helps maintain skin integrity and moisture. Following a reduced-calorie, reduced-fat diet (Choice B) may be beneficial for weight management but is not directly related to skin care. Inspecting involved areas daily for new ulcerations (Choice C) is important for skin assessment and early intervention but does not specifically address dry skin. Instructing the client to limit activities of daily living (ADLs) (Choice D) is not necessary for addressing dry skin; in fact, promoting mobility and circulation through appropriate activities is crucial.

3. The client with chronic renal failure is on a fluid restriction. Which of the following statements by the client indicates that the teaching has been effective?

• A. I will limit my fluid intake to prevent fluid overload.
• B. I can drink as much fluid as I want as long as I take my medication.
• C. I will skip dialysis sessions if I feel tired.
• D. I will limit my fluid intake to 1 liter per day.

Correct answer: A

Rationale: Choice A is the correct answer because it demonstrates the client's understanding of the need to limit fluid intake to prevent fluid overload, which is crucial in managing chronic renal failure. Adequate fluid restriction is essential to prevent complications such as fluid overload and electrolyte imbalances. Choice B is incorrect as it promotes excessive fluid intake, which can worsen the client's condition by putting additional stress on the kidneys. Choice C is incorrect as skipping dialysis sessions can lead to a buildup of toxins in the body, worsening renal failure and potentially leading to life-threatening complications. Choice D is incorrect because limiting fluid intake to a specific volume may not be appropriate for all clients and can vary depending on individual needs, medical condition, and healthcare provider recommendations.

4. The patient is being educated on taking hydrochlorothiazide. Which statement by the patient indicates a need for further teaching?

• A. I may need additional sodium and calcium while taking this medication.
• B. I should consume plenty of fruits and vegetables while taking this drug.
• C. I should be cautious when getting up from a bed or chair while on this medication.
• D. I will take the medication in the morning to reduce certain side effects.

Correct answer: A

Rationale: The correct answer is A because patients do not require extra sodium or calcium while taking hydrochlorothiazide, a thiazide diuretic. This medication actually promotes the excretion of sodium and water. Choices B, C, and D are correct statements regarding the use of hydrochlorothiazide. Patients are encouraged to have a diet rich in fruits and vegetables, be careful with position changes due to potential orthostatic hypotension, and take the medication in the morning to reduce the need for frequent urination during nighttime.

5. Which of the following is a common cause of acute kidney injury?

• A. Hypertension
• B. Dehydration
• C. Infection
• D. Hypotension

Correct answer: C

Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.
