Nursing Elites

1. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

2. A client with heart failure receiving furosemide develops muscle weakness. What is the nurse's priority action?

• A. Administer potassium supplements as prescribed.
• B. Monitor the client’s potassium levels.
• C. Instruct the client to increase their salt intake.
• D. Discontinue the furosemide.

Correct answer: B

Rationale: Muscle weakness in a client receiving furosemide (a diuretic) is often a sign of hypokalemia, as furosemide increases potassium loss. Monitoring potassium levels is essential to identify and address any imbalances and prevent complications such as arrhythmias. Administering potassium supplements without monitoring the levels can lead to hyperkalemia, which has its own set of serious complications. Instructing the client to increase salt intake is not appropriate in this situation as it does not address the underlying electrolyte imbalance. Discontinuing furosemide abruptly can worsen heart failure symptoms; therefore, monitoring potassium levels and adjusting the treatment accordingly is the most appropriate action.

3. An older adult client with eye dryness reports itching and excessive tearing. Which medication group is most likely to have produced this client's symptoms?

• A. Antiinfectives and antidepressants.
• B. Anticoagulants and antihistamines.
• C. Antiretrovirals and antivirals.
• D. Antihypertensives and anticholinergics.

Correct answer: D

Rationale: The correct answer is D: Antihypertensives and anticholinergics. Anticholinergics are known to cause dryness of secretions, including dry eyes, which can lead to symptoms of eye dryness, itching, and excessive tearing as reported by the client. Choices A, B, and C are incorrect as they do not typically cause the symptoms described by the client. Antiinfectives, antidepressants, anticoagulants, antihistamines, antiretrovirals, and antivirals do not commonly lead to dry eyes, itching, and excessive tearing.

4. A client with asthma is prescribed an inhaled corticosteroid. What teaching should the nurse provide?

• A. Rinse the mouth with water after using the inhaler.
• B. Take the medication only during asthma attacks.
• C. Avoid using the inhaler before exercise.
• D. Clean the inhaler with hot water after each use.

Correct answer: A

Rationale: The correct teaching the nurse should provide to a client prescribed an inhaled corticosteroid is to rinse the mouth with water after using the inhaler. This helps prevent oral fungal infections, a common side effect of inhaled corticosteroids. Choice B is incorrect because inhaled corticosteroids are usually used regularly, not just during asthma attacks. Choice C is incorrect as using the inhaler before exercise can actually help prevent exercise-induced bronchospasm. Choice D is incorrect because cleaning the inhaler with hot water after each use is not necessary and may damage the device.

5. Before administering digoxin to a client with heart failure, what is the most important assessment for the nurse to perform?

• A. Check the client's blood pressure
• B. Monitor the client's heart rate
• C. Assess the client's respiratory rate
• D. Review the client's potassium level

Correct answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.
