Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. When reconstituted, how many milligrams are in each milliliter of solution?

• A. 300 mg/mL
• B. 350 mg/mL
• C. 450 mg/mL
• D. 400 mg/mL

Correct answer: D

Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.

3. The nurse is assessing a newborn and notes that the infant has a yellowish tint to the skin. What should the nurse do next?

• A. Reassure the parents that this is normal
• B. Monitor the infant's bilirubin levels
• C. Increase the frequency of feedings
• D. Administer phototherapy

Correct answer: B

Rationale: When a newborn presents with a yellowish tint to the skin, it can indicate jaundice, which is caused by elevated bilirubin levels. Monitoring the infant's bilirubin levels is crucial to assess the severity of jaundice and determine the need for further intervention. Reassuring the parents without proper assessment could lead to delayed treatment if jaundice is present. Increasing the frequency of feedings may not address the underlying cause of jaundice. Administering phototherapy is a treatment option that should be based on bilirubin level assessment and healthcare provider's recommendation.

4. A client who is 24 weeks pregnant presents with a complaint of feeling dizzy when lying on her back. What is the best response by the nurse?

• A. Advise the client to lie on her side
• B. Encourage the client to drink more fluids
• C. Suggest the client elevate her legs when lying down
• D. Recommend the client take short walks throughout the day

Correct answer: A

Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.

5. The client with heart failure is prescribed furosemide (Lasix). What should the nurse include in the teaching plan?

• A. Increase potassium-rich foods in the diet
• B. Avoid foods high in sodium
• C. Monitor fluid intake and adjust as needed
• D. Take the medication in the morning

Correct answer: A

Rationale: The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.
