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. A client with overflow incontinence needs assistance with elimination. What intervention should the nurse include in the plan of care?

• A. Stroke the medial aspect of the thigh.
• B. Use intermittent catheterization.
• C. Provide digital anal stimulation.
• D. Use the Valsalva maneuver.

Correct answer: D

Rationale: In clients with overflow incontinence, the voiding reflex arc is impaired. The Valsalva maneuver, which involves holding the breath and bearing down as if to defecate, can help initiate voiding by applying mechanical pressure. Options A and C (stroking the thigh or anal stimulation) rely on an intact reflex arc to trigger elimination and are not effective for clients with overflow incontinence. Intermittent catheterization (Option B) is a last resort due to the high risk of infection and should only be considered if other interventions fail.

3. 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.

4. The nurse is planning care for an older adult client who experienced a cerebrovascular accident several weeks ago. The client has expressive aphasia and often becomes frustrated with the nursing staff. Which intervention should the nurse implement?

• A. Teach the client the use of basic sign language
• B. Speak slowly to the client
• C. Encourage the client's use of picture charts
• D. Ask the client simple questions

Correct answer: C

Rationale: Encouraging the client's use of picture charts is the most appropriate intervention for a client with expressive aphasia. Picture charts provide visual cues that can aid in communication and reduce frustration for the client. This intervention can help the client express their needs and thoughts effectively. Teaching sign language (Choice A) may be challenging and not as practical in this situation as it may not address the specific communication barriers caused by expressive aphasia. Speaking slowly (Choice B) may not fully address the communication difficulties associated with expressive aphasia. Asking simple questions (Choice D) may not be effective as the client may have difficulty understanding and responding due to the nature of expressive aphasia.

5. A client in the intensive care unit is started on continuous venovenous hemofiltration (CVVH). Which finding should prompt immediate action by the nurse?

• A. Blood pressure of 76/58 mm Hg
• B. Sodium level of 138 mEq/L
• C. Potassium level of 5.5 mEq/L
• D. Pulse rate of 90 beats/min

Correct answer: A

Rationale: The correct answer is A: Blood pressure of 76/58 mm Hg. In a client undergoing continuous venovenous hemofiltration (CVVH), hypotension can be a significant concern if replacement fluid does not adequately maintain blood pressure. The nurse should take immediate action to address hypotension to prevent further complications. The sodium level of 138 mEq/L is within normal range, and a potassium level of 5.5 mEq/L, while slightly elevated, may be expected in a patient with acute kidney injury. A pulse rate of 90 beats/min falls within the normal range and does not typically require immediate intervention in this context.
