Nursing Elites

1. A client has been scheduled for magnetic resonance imaging (MRI). For which of the following conditions, a contraindication to MRI, does the nurse check the client’s medical history?

• A. Pancreatitis
• B. Pacemaker insertion
• C. Type 1 diabetes mellitus
• D. Chronic airway limitation

Correct answer: B

Rationale: The correct answer is B: Pacemaker insertion. Patients with metal devices or implants are contraindicated for MRI. These include pacemakers, orthopedic hardware, artificial heart valves, aneurysm clips, and intrauterine devices. These metal objects can be affected by the strong magnetic field of the MRI, leading to serious risks for the patient. Pancreatitis (choice A), Type 1 diabetes mellitus (choice C), and chronic airway limitation (choice D) are not contraindications to MRI based on the presence of metal objects. Therefore, the nurse should be particularly concerned about pacemaker insertion when reviewing the client's medical history prior to an MRI.

2. The client with chronic renal failure is receiving instruction on dietary restrictions. Which of the following food items should the client be instructed to avoid?

• A. Bananas.
• B. Apples.
• C. Rice.
• D. Potatoes.

Correct answer: A

Rationale: The correct answer is A: Bananas. Bananas are high in potassium, and individuals with chronic renal failure are often advised to limit potassium intake to prevent hyperkalemia. Apples, rice, and potatoes are lower in potassium and can be included in moderation in the diet of clients with chronic renal failure.

3. A client is receiving Cilostazol (Pletal) for peripheral arterial disease causing intermittent claudication. The nurse determines this medication is effective when the client reports which of the following?

• A. I am having fewer aches and pains.
• B. I do not have headaches anymore.
• C. I am able to walk further without leg pain.
• D. My toes are turning grayish black in color.

Correct answer: C

Rationale: The correct answer is C. Cilostazol improves blood flow to the muscles, which helps alleviate symptoms of intermittent claudication. An improvement in walking distance without leg pain indicates the effectiveness of the medication. Choices A and B are not directly related to the expected outcome of Cilostazol therapy for intermittent claudication. Choice D is concerning for a potential adverse effect and should be reported to the healthcare provider immediately.

4. The nurse is preparing to administer the first dose of hydrochlorothiazide (HydroDIURIL) 50 mg to a patient who has a blood pressure of 160/95 mm Hg. The nurse notes that the patient had a urine output of 200 mL in the past 12 hours. The nurse will perform which action?

• A. Administer the medication as ordered.
• B. Encourage the patient to drink more fluids.
• C. Hold the medication and request an order for serum BUN and creatinine.
• D. Request an order for serum electrolytes and administer the medication.

Correct answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

5. A nurse reviews a female client’s laboratory results. Which result from the client’s urinalysis should the nurse recognize as abnormal?

• A. pH 5.6
• B. Ketone bodies present
• C. Specific gravity of 1.020
• D. Clear and yellow color

Correct answer: B

Rationale: The correct answer is B: Ketone bodies present. Ketone bodies in urine indicate abnormal metabolism, specifically the incomplete breakdown of fatty acids. Normally, there should be no ketones present in urine. Ketone bodies are produced when the body uses fat sources instead of glucose for cellular energy. A pH range between 4.6 and 8, a specific gravity between 1.005 and 1.030, and clear yellow color in urine are considered normal findings for a female client’s urinalysis. Therefore, options A, C, and D are within normal ranges and not indicative of abnormal results in the urinalysis.
