Nursing Elites

1. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.

2. The client is being educated by the nurse on home blood glucose monitoring. Which of the following blood glucose measurements indicates hypoglycemia?

• A. 59 mg/dL (3.3 mmol/L)
• B. 75 mg/dL (4.2 mmol/L)
• C. 108 mg/dL (6 mmol/L)
• D. 119 mg/dL (6.6 mmol/L)

Correct answer: A

Rationale: A blood glucose level of 59 mg/dL (3.3 mmol/L) is considered hypoglycemia, which is an abnormally low blood sugar level. This level requires immediate attention as it can lead to symptoms such as confusion, shakiness, and even loss of consciousness if left untreated. Choices B, C, and D have blood glucose levels within the normal range or slightly higher, indicating euglycemia or normal blood sugar levels, and not hypoglycemia.

3. A 57-year-old male client is scheduled to have a stress-thallium test the following morning and is NPO after midnight. At 0130, he is agitated because he cannot eat and is demanding food. Which response is best for the nurse to provide to this client?

• A. I'm sorry sir, you have a prescription for nothing by mouth from midnight tonight.
• B. I will let you have one cracker, but that is all you can have for the rest of tonight.
• C. What did the healthcare provider tell you about the test you are having tomorrow?
• D. The test you are having tomorrow requires that you have nothing by mouth tonight.

Correct answer: D

Rationale: Being direct and explaining to the client that the test requires him to be NPO, is the most therapeutic statement because the nurse is responding to the client's question and providing him the reason why.

4. A client who has developed acute kidney injury (AKI) due to an aminoglycoside antibiotic has moved from the oliguric phase to the diuretic phase of AKI. Which parameters are most important for the nurse to plan to carefully monitor?

• A. Side effects of total parenteral nutrition (TPN) and Intralipids.
• B. Uremic irritation of mucous membranes and skin surfaces.
• C. Elevated creatinine and blood urea nitrogen (BUN).
• D. Hypovolemia and electrocardiographic (ECG) changes.

Correct answer: D

Rationale: During the diuretic phase of acute kidney injury (AKI), monitoring for hypovolemia and electrocardiographic (ECG) changes is crucial. Hypovolemia can occur due to the increased urine output in this phase, potentially leading to dehydration and electrolyte imbalances. Electrolyte imbalances can result in ECG changes, such as arrhythmias, which can be life-threatening. Therefore, careful monitoring of fluid status and ECG findings helps in preventing complications. Choices A, B, and C are not the most crucial parameters to monitor during the diuretic phase of AKI. Side effects of total parenteral nutrition (TPN) and Intralipids, uremic irritation of mucous membranes and skin surfaces, and elevated creatinine and blood urea nitrogen (BUN) are important considerations in other phases of AKI or in other conditions, but they are not the primary focus during the diuretic phase when hypovolemia and ECG changes take precedence.

5. The healthcare professional is preparing to give a dose of trimethoprim-sulfamethoxazole (TMP-SMX) and learns that the patient takes warfarin (Coumadin). The healthcare professional will request an order for

• A. a decreased dose of TMP-SMX.
• B. a different antibiotic.
• C. an increased dose of warfarin.
• D. coagulation studies.

Correct answer: D

Rationale: Sulfonamides, like trimethoprim-sulfamethoxazole (TMP-SMX), can potentiate the anticoagulant effects of warfarin (Coumadin). To monitor the patient's response and prevent adverse effects, the healthcare professional should request coagulation studies, such as International Normalized Ratio (INR) levels. Choosing a decreased dose of TMP-SMX would not address the potential drug interaction between TMP-SMX and warfarin. Opting for a different antibiotic is not necessary if the interaction can be managed by monitoring. Increasing the dose of warfarin without monitoring could lead to excessive anticoagulation and adverse events, so it's not the appropriate action in this scenario.
