Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

• A. Dehydration is treated with calcium supplements
• B. Dehydration can increase the risk of preterm labor
• C. Dehydration can increase gastroesophageal reflux
• D. Dehydration is caused by a decreased hemoglobin and hematocrit

Correct answer: B

Rationale: The correct statement the nurse should make is that dehydration can increase the risk of preterm labor. Dehydration reduces amniotic fluid and uterine blood flow, potentially leading to preterm contractions. Choice A is incorrect because dehydration is not treated with calcium supplements but rather with adequate fluid intake. Choice C is incorrect as dehydration does not directly increase gastroesophageal reflux. Choice D is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by insufficient fluid intake or excessive fluid loss.

3. A nurse is reviewing the medical record of a client who has a history of angina and is scheduled for surgery. Which of the following findings should the nurse report to the provider?

• A. Serum potassium level of 4.2 mEq/L
• B. Blood pressure of 138/84 mm Hg
• C. Platelet count of 150,000/mm³
• D. INR of 2.0

Correct answer: D

Rationale: The correct answer is D. An INR of 2.0 is within the therapeutic range for clients receiving warfarin. It is crucial to report this finding to the provider before surgery to ensure appropriate management and potential adjustments to prevent excessive bleeding risks. Choices A, B, and C are within normal limits and do not directly impact the client's surgery preparation or risk for bleeding, so they do not require immediate reporting.

4. A charge nurse on a medical-surgical unit is planning assignments for a licensed practical nurse (LPN) who has been sent from the unit due to a staffing shortage. Which of the following clients should the nurse delegate to the LPN?

• A. A client who has an Hgb of 6.3 g/dl and a prescription for packed RBCs.
• B. A client who sustained a concussion and has unequal pupils.
• C. A client who is postoperative following a bowel resection with an NG tube.
• D. A client who fractured his femur yesterday and is experiencing shortness of breath.

Correct answer: C

Rationale: The correct answer is C because a client who is postoperative following a bowel resection with an NG tube can be delegated to an LPN as this involves routine postoperative care. Option A involves administering packed RBCs which requires assessment and monitoring for potential adverse reactions, not suitable for delegation to an LPN. Option B requires neurological assessment and close monitoring due to the concussion, which is beyond the scope of an LPN. Option D involves a client with a recent fracture and shortness of breath, which requires urgent assessment and intervention beyond the LPN's scope of practice.

5. A healthcare professional is assessing a client who has a new prescription for digoxin. Which of the following findings is the priority for the healthcare professional to report to the provider?

• A. Heart rate of 58/min
• B. Weight gain of 1 kg (2.2 lb) in 24 hours
• C. Respiratory rate of 20/min
• D. Temperature of 37.3°C (99.1°F)

Correct answer: A

Rationale: The correct answer is A. A heart rate of 58/min is indicative of bradycardia, a potential sign of digoxin toxicity, which should be reported immediately. While weight gain, respiratory rate, and temperature are important parameters to monitor, they are not as critical as identifying bradycardia in a client taking digoxin.
