Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease and a serum potassium level of 6.5 mEq/L. Which of the following actions should the nurse take?

• A. Administer sodium bicarbonate
• B. Administer sodium polystyrene sulfonate
• C. Administer calcium gluconate
• D. Administer calcium carbonate

Correct answer: B

Rationale: The correct action for the nurse to take is to administer sodium polystyrene sulfonate. This medication promotes potassium excretion and helps lower serum potassium levels in clients with hyperkalemia, which is indicated by a high potassium level. Sodium bicarbonate (choice A) is not used to treat hyperkalemia. Calcium gluconate (choice C) and calcium carbonate (choice D) are used to manage hyperkalemia by stabilizing cell membranes but are not the initial treatment choice for lowering potassium levels.

2. A nurse is caring for a client who has deep vein thrombosis. Which of the following instructions should the nurse include in the plan of care?

• A. Limit the client's fluid intake to 1500 mL per day.
• B. Avoid massaging the affected extremity to relieve pain.
• C. Do not apply cold packs to the client's affected extremity.
• D. Elevate the client's affected extremity when in bed.

Correct answer: D

Rationale: The correct answer is to elevate the client's affected extremity when in bed. Elevating the extremity helps to reduce swelling and improve venous return in clients with DVT. Limiting fluid intake to 1500 mL per day (Choice A) is not directly related to managing DVT. Massaging the affected extremity (Choice B) can dislodge a clot and lead to serious complications. Applying cold packs (Choice C) can vasoconstrict blood vessels, potentially worsening the condition by reducing blood flow.

3. A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which statement should the nurse make?

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

Correct answer: B

Rationale: The correct statement is B: 'Dehydration can increase the risk of preterm labor.' Dehydration can lead to increased uterine irritability, potentially causing preterm contractions and labor. Choice A is incorrect as dehydration is not treated with calcium supplements but rather with fluids. Choice C is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by a lack of fluids. Choice D is incorrect as dehydration does not directly cause gastroesophageal reflux.

4. A nurse is caring for a client who is experiencing acute alcohol withdrawal. Which of the following medications should the nurse plan to administer?

• A. Lorazepam
• B. Atenolol
• C. Naltrexone
• D. Methadone

Correct answer: A

Rationale: Lorazepam is the correct choice for managing acute alcohol withdrawal symptoms due to its effectiveness in controlling agitation and tremors associated with this condition. Atenolol (Choice B) is a beta-blocker mainly used for hypertension and angina, not for alcohol withdrawal symptoms. Naltrexone (Choice C) is used for alcohol dependence treatment by reducing cravings and the rewarding effects of alcohol, but it is not typically used in acute withdrawal situations. Methadone (Choice D) is an opioid agonist mainly used for opioid detoxification and maintenance therapy, not for alcohol withdrawal.

5. A healthcare professional is preparing to administer an IV fluid bolus of 500 mL over 4 hours to a client who is dehydrated. The healthcare professional should set the IV pump to deliver how many mL/hr?

• A. 75 mL/hr.
• B. 100 mL/hr.
• C. 125 mL/hr.
• D. 150 mL/hr.

Correct answer: C

Rationale: Setting the IV pump to 125 mL/hr ensures the correct infusion rate for delivering 500 mL over 4 hours. To calculate the mL/hr rate, divide the total volume to be infused (500 mL) by the total time for infusion (4 hours): 500 mL / 4 hours = 125 mL/hr. Choice A (75 mL/hr) is too low and would result in an insufficient infusion rate, potentially delaying fluid resuscitation. Choice B (100 mL/hr) would also be too low and not deliver the fluid within the specified time frame. Choice D (150 mL/hr) is too high and would infuse the fluid too quickly, potentially causing fluid overload and complications.
