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 caring for a client who has chronic obstructive pulmonary disease (COPD) and is experiencing dyspnea. Which of the following actions should the nurse take?

• A. Encourage the client to take deep breaths.
• B. Place the client in a high-Fowler's position.
• C. Administer a bronchodilator.
• D. Administer oxygen at 6 L/min via face mask.

Correct answer: B

Rationale: The correct answer is to place the client in a high-Fowler's position. This position helps improve breathing by expanding the lungs and aiding in better oxygenation. Encouraging the client to take deep breaths may not be effective in managing dyspnea in COPD as it can lead to fatigue. Administering a bronchodilator may be necessary but placing the client in a high-Fowler's position should be the priority. Administering oxygen at 6 L/min via face mask may also be needed, but positioning is the initial intervention to optimize respiratory function.

3. A nurse is assessing a client who has just received an opioid medication. Which of the following findings should the nurse monitor first?

• A. Constipation.
• B. Drowsiness.
• C. Orthostatic hypotension.
• D. Respiratory depression.

Correct answer: D

Rationale: When a client receives an opioid medication, the nurse should first monitor for respiratory depression as it is a life-threatening adverse effect associated with opioids. This can lead to inadequate ventilation and hypoxia, requiring immediate intervention. Constipation, drowsiness, and orthostatic hypotension are also common side effects of opioids but are not as immediately life-threatening as respiratory depression.

4. A client is receiving heparin therapy. Which of the following laboratory results indicates the client is receiving an effective dose of heparin?

• A. INR 1.5
• B. aPTT 60 seconds
• C. Platelets 150,000/mm³
• D. Potassium 4.0 mEq/L

Correct answer: B

Rationale: An aPTT of 60 seconds indicates the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for a clot to form, and a therapeutic range for heparin therapy is usually 1.5 to 2 times the control value, which is around 60-80 seconds. An INR of 1.5 is not related to heparin therapy, as it is commonly used to monitor warfarin therapy. Platelet count and potassium levels are not direct indicators of the effectiveness of heparin therapy.

5. What is the initial step when a patient is experiencing chest pain?

• A. Administer oxygen
• B. Reposition the patient
• C. Provide pain relief
• D. Provide nitroglycerin

Correct answer: A

Rationale: Administering oxygen is the initial step in managing chest pain. Oxygen helps improve oxygenation levels in the blood, which is crucial in cases of chest pain. Repositioning the patient, providing pain relief, or administering nitroglycerin may be necessary steps depending on the underlying cause, but administering oxygen takes precedence as it addresses the primary concern of oxygen supply to the body during chest pain.
