Nursing Elites

1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning to the nurse?

• A. Serum glucose of 500 mg/dL
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS) as it indicates severe dehydration and hypertonicity. This high serum osmolarity level can lead to neurological complications and requires immediate intervention to prevent further deterioration. Serum glucose levels, blood pressure, and serum pH are important parameters to monitor in HHS, but a significantly elevated serum osmolarity poses a higher risk of complications and warrants urgent attention. High serum glucose levels, like 500 mg/dL, are expected in HHS but do not directly indicate the severity of dehydration. Blood pressure of 140/90 mmHg is within normal limits and may not be directly related to the acute complications of HHS. A serum pH of 7.30 suggests acidosis, which is important to address but may not be as immediately concerning as severe dehydration indicated by high serum osmolarity.

2. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

3. A client with a postoperative wound that eviscerated yesterday has an elevated temperature. Which intervention is most important for the nurse to implement?

• A. Initiate contact isolation.
• B. Obtain a wound swab for culture and sensitivity.
• C. Assess temperature every 4 hours.
• D. Use alcohol-based solutions for hand hygiene.

Correct answer: B

Rationale: In this scenario, the most critical intervention is to obtain a wound swab for culture and sensitivity. This will help identify the causative organism present in the wound, enabling healthcare providers to prescribe the appropriate treatment. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case where infection is suspected. Assessing the temperature (Choice C) is important for monitoring the client's condition but does not address the underlying cause. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but does not directly address the client's specific condition of a postoperative wound with evisceration and elevated temperature.

4. The nurse is caring for a client with end-stage renal disease (ESRD) who is scheduled for hemodialysis. Which assessment finding is most concerning?

• A. Blood pressure of 110/70 mmHg
• B. Heart rate of 110 beats per minute
• C. Fever of 100.4°F
• D. Respiratory rate of 24 breaths per minute

Correct answer: C

Rationale: A fever of 100.4°F is the most concerning assessment finding in a client with ESRD scheduled for hemodialysis. This elevation in temperature may indicate an underlying infection, which can lead to serious complications in individuals with compromised renal function. Prompt intervention is necessary to prevent the spread of infection and deterioration of the client's condition. The other vital signs mentioned, such as blood pressure, heart rate, and respiratory rate, while important to monitor, are within acceptable ranges and do not pose an immediate threat like a fever indicative of infection.

5. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.
