Nursing Elites

1. The home health nurse provides teaching about insulin self-injection to a client who was recently diagnosed with diabetes mellitus. When the client begins to perform a return demonstration of an insulin injection into the abdomen, which instruction should the nurse provide?

• A. Select a different injection site
• B. Continue with the insulin injection
• C. Keep the skin flat rather than bunched
• D. Lie down flat for better skin exposure

Correct answer: B

Rationale: Choosing to continue with the insulin injection is the correct instruction in this scenario because it allows the client to demonstrate proper technique and reinforces their learning. Selecting a different injection site (choice A) is not necessary if the client is injecting into the abdomen as it is a suitable site. Keeping the skin flat rather than bunched (choice C) is a good practice but is not the priority in this situation where the client is demonstrating the injection technique. Lying down flat for better skin exposure (choice D) is not required and may not be practical for the client during routine self-injections.

2. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 62, PaCO2 59, and HCO3. Which statement describes the most likely cause of the simultaneous increase in both the PaO2 and the PaCO2?

• A. The hypercapnia resulted from the rapid respirations.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client had a pneumothorax which restricted ventilation.
• D. The client had a pulmonary embolism that reduced perfusion.

Correct answer: B

Rationale: In patients with COPD, oxygen therapy can reduce the hypoxic drive, which is the primary stimulus for breathing in these individuals. By providing supplemental oxygen, the hypoxic drive is diminished, resulting in decreased respiratory effort. As a consequence, the PaO2 may increase due to the supplemental oxygen, but this can lead to a decrease in the respiratory drive and subsequent retention of carbon dioxide, causing an increase in PaCO2 levels. Option A is incorrect because rapid respirations would typically lower PaCO2 levels. Option C is incorrect as a pneumothorax would lead to impaired gas exchange and decreased PaO2 levels without necessarily affecting PaCO2 levels. Option D is incorrect as a pulmonary embolism would typically result in ventilation-perfusion mismatch and decreased PaO2 levels without directly impacting PaCO2 levels.

3. A 20-year-old female client calls the nurse to report a lump she found in her breast. Which response is the best for the nurse to provide?

• A. Check it again in one month, and if it is still there schedule an appointment.
• B. Most lumps are benign, but it is always best to come in for an examination.
• C. Try not to worry too much about it, because usually, most lumps are benign.
• D. If you are in your menstrual period it is not a good time to check for lumps.

Correct answer: B

Rationale: The nurse advising the client to come in provides the best response because it addresses the client's anxiety most effectively and encourages prompt and immediate action for a potential problem.

4. A client is placed on fluid restrictions because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client’s fluid balance is stable at this time?

• A. Decreased calcium levels
• B. Increased phosphorus levels
• C. No adventitious sounds in the lungs
• D. Increased edema in the legs

Correct answer: C

Rationale: The absence of adventitious sounds upon auscultation of the lungs is a key indicator that the client's fluid balance is stable. Adventitious sounds, such as crackles or wheezes, are typically heard in conditions of fluid overload, indicating that the body is retaining excess fluid. Choices A and B, decreased calcium levels and increased phosphorus levels, are common laboratory findings associated with chronic kidney disease (CKD) and are not directly related to fluid balance. Increased edema in the legs is a sign of fluid imbalance, suggesting fluid retention in the tissues, which would not indicate stable fluid balance in a client with CKD on fluid restrictions.

5. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?

• A. Drugs with a broad spectrum
• B. Drugs with a narrow spectrum
• C. Drugs with a broad therapeutic index
• D. Drugs with a narrow therapeutic index

Correct answer: D

Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.
