Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has Cushing's disease. The nurse should expect an increase in which of the following laboratory values?

• A. Serum glucose level
• B. Serum potassium level
• C. Serum calcium level
• D. Serum sodium level

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is increased cortisol production, leading to elevated blood glucose levels. This occurs due to the role of cortisol in promoting gluconeogenesis and insulin resistance. Choices B, C, and D are incorrect because Cushing's disease is not typically associated with alterations in serum potassium, calcium, or sodium levels.

2. A nurse is preparing to assess a 2-week-old newborn. Which of the following actions should the nurse plan to take?

• A. Obtain the newborn's body temperature using a tympanic thermometer
• B. Pull the pinna of the infant's ear forward before inserting the probe
• C. Auscultate the newborn's apical pulse for 60 seconds
• D. Measure the newborn's head circumference over the eyebrows and below the occipital prominence

Correct answer: C

Rationale: The correct answer is C: Auscultate the newborn's apical pulse for 60 seconds. When assessing a newborn, it is essential to auscultate the apical pulse for a full 60 seconds to accurately determine their heart rate. This method allows for a more precise measurement, considering the variability in heart rates in newborns. Choice A is incorrect because tympanic thermometers are not typically used for newborns due to their ear canals being small and not fully developed. Choice B is incorrect as pulling the pinna forward is not necessary for assessing the apical pulse. Choice D is incorrect as measuring head circumference involves a different assessment and is not relevant to determining the heart rate of a newborn.

3. A client with diabetes mellitus is being taught by a nurse about managing blood glucose levels. Which of the following client statements indicates an understanding of the teaching?

• A. I will eat a snack if my blood glucose level is below 70 mg/dL.
• B. I will take my insulin if my blood glucose level is above 200 mg/dL.
• C. I will check my blood glucose level once a week.
• D. I will take my insulin only when I feel symptoms of hyperglycemia.

Correct answer: A

Rationale: Choice A is the correct answer because consuming a snack when the blood glucose level is below 70 mg/dL helps prevent hypoglycemia in clients with diabetes mellitus. Choice B is incorrect because taking insulin when blood glucose is high (above 200 mg/dL) helps manage hyperglycemia, not hypoglycemia. Choice C is incorrect as checking blood glucose levels once a week is insufficient for proper diabetes management, which typically requires more frequent monitoring. Choice D is incorrect because waiting for symptoms of hyperglycemia to take insulin can lead to uncontrolled blood glucose levels.

4. What is the best intervention for a patient presenting with respiratory distress?

• A. Administer oxygen
• B. Administer bronchodilators
• C. Reposition the patient
• D. Provide humidified air

Correct answer: A

Rationale: Administering oxygen is the most critical intervention for a patient in respiratory distress as it helps improve oxygenation levels. Oxygen therapy aims to increase oxygen saturation in the blood, providing relief and support during episodes of respiratory distress. Administering bronchodilators may be beneficial in some cases, but oxygen therapy takes precedence in addressing the underlying issue of inadequate oxygenation. Repositioning the patient may help optimize ventilation but does not directly address the primary need for increased oxygen. Providing humidified air can offer comfort but does not address the urgent need for improved oxygen levels in a patient experiencing respiratory distress.

5. How should a healthcare professional care for a patient with a stage 2 pressure ulcer?

• A. Clean the area with normal saline
• B. Apply antibiotic ointment
• C. Use a hydrocolloid dressing
• D. Change the dressing daily

Correct answer: C

Rationale: Using a hydrocolloid dressing is the appropriate care for a stage 2 pressure ulcer because it provides a moist healing environment, promotes healing, and helps to prevent infection. Cleaning the area with normal saline (Choice A) is important but not the primary treatment for a stage 2 pressure ulcer. Applying antibiotic ointment (Choice B) may not be necessary unless there is a sign of infection. Changing the dressing daily (Choice D) may disrupt the healing process and is not recommended unless the dressing is soiled or compromised.
