Nursing Elites

1. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

2. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

• A. Pulse oximetry reading of 94%
• B. Heart rate increases from 80 to 90 beats per minute
• C. Respiratory rate increases from 16 to 20 breaths per minute
• D. Client reports increased energy levels

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.

3. The nurse is providing care for a client with heart failure who is prescribed furosemide. Which laboratory value should the nurse monitor closely?

• A. Calcium level
• B. Sodium level
• C. Magnesium level
• D. Potassium level

Correct answer: D

Rationale: The correct answer is D: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. While calcium, sodium, and magnesium levels are important in various conditions and treatments, they are not the primary electrolyte affected by furosemide.

4. A toddler presenting with a history of intermittent skin rashes, hives, abdominal pain, and vomiting that occurs after ingesting milk products arrives at the clinic accompanied by the parents. Which type of testing should the nurse educate the toddler's family about?

• A. Complete blood count
• B. Lactose tolerance test
• C. Skin allergy testing
• D. Serum immunoglobulin E

Correct answer: D

Rationale: The correct answer is D, Serum immunoglobulin E (IgE) testing. This test can help diagnose food allergies, including milk protein allergies, in toddlers presenting with symptoms like skin rashes, hives, abdominal pain, and vomiting after consuming milk products. Skin allergy testing is used for allergies but may not be suitable for this age group due to developmental factors. Lactose intolerance, which is different from a milk allergy, is assessed through a lactose tolerance test, not IgE testing. A complete blood count (CBC) would not provide specific information related to food allergies.

5. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.
