Nursing Elites

1. A newborn is having difficulty maintaining a temperature above 98 degrees Fahrenheit and has been placed in a warming isolette. Which action is a nursing priority?

• A. Protect the neonate's eyes from the heat lamp
• B. Monitor the neonate's temperature
• C. Warm all medications and liquids before administration
• D. Avoid touching the neonate with cold hands

Correct answer: B

Rationale: When a newborn is placed in a warming isolette due to difficulty maintaining temperature, the priority action is to continuously monitor the neonate's temperature to prevent overheating. Using heat lamps is unsafe as their temperature cannot be regulated, potentially causing harm. Warming medications and fluids before administration is not necessary in this situation. While touching the neonate with cold hands may startle them, it does not pose a safety risk compared to monitoring and controlling the temperature.

2. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

• A. The patient is allergic to shellfish.
• B. The patient has a pacemaker.
• C. The patient suffers from claustrophobia.
• D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.

3. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

4. Which food should the assistive personnel be instructed to remove from the child's food tray based on the prescribed treatment for nephrotic syndrome?

• A. Pickle
• B. Wheat toast
• C. Baked chicken
• D. Steamed vegetables

Correct answer: A

Rationale: In nephrotic syndrome, a no-added-salt diet is recommended to manage the condition. High-sodium foods like pickles should be avoided as they can exacerbate fluid retention and swelling. Wheat toast, baked chicken, and steamed vegetables are generally suitable for individuals with nephrotic syndrome as they are low in sodium and protein, which are important considerations for this condition. Therefore, the correct choice is to remove the pickles from the child's food tray.

5. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.
