Nursing Elites

1. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.

2. A nurse is reviewing a prescription for doxazosin with a client. Which instruction should the nurse include?

• A. Decrease caloric intake to reduce weight gain
• B. Increase dietary fiber to prevent constipation
• C. Rise slowly when sitting up
• D. Take this medication each morning

Correct answer: C

Rationale: The correct answer is C: 'Rise slowly when sitting up.' Doxazosin can cause orthostatic hypotension, a sudden drop in blood pressure when standing up, leading to dizziness or fainting. Instructing the client to rise slowly helps prevent this adverse effect. Choices A, B, and D are incorrect. A decrease in caloric intake to reduce weight gain, an increase in dietary fiber to prevent constipation, and taking the medication each morning are not specific instructions related to managing the side effects of doxazosin.

3. A nurse is discussing immunity with a client who has received an immunization. The nurse should identify that an immunization functions as part of which of the following types of immunity?

• A. Innate immunity
• B. Passive immunity
• C. Acquired immunity
• D. Natural immunity

Correct answer: C

Rationale: Immunizations provide acquired immunity. They work by introducing antigens into the body, which triggers the immune system to produce antibodies specific to that antigen. Choice A, 'Innate immunity,' refers to the natural defense mechanisms an organism is born with and does not involve immunizations. Choice B, 'Passive immunity,' is the transfer of pre-formed antibodies and does not involve immunizations. Choice D, 'Natural immunity,' is a general term that encompasses all immunity that is not acquired through deliberate immunization or passive transfer of antibodies.

4. A nurse is providing teaching to a client who has a new prescription for lisinopril. Which of the following statements by the client indicates a need for further teaching?

• A. I will notify my doctor if I develop a cough.
• B. I will avoid using salt substitutes.
• C. I will increase my intake of potassium-rich foods.
• D. I will monitor my blood pressure regularly.

Correct answer: C

Rationale: The correct answer is C. Clients taking lisinopril should avoid potassium-rich foods because ACE inhibitors can increase potassium levels, potentially leading to hyperkalemia. Choices A, B, and D are all correct statements. Clients should notify their doctor if they develop a cough as it can indicate a potential side effect of lisinopril. Avoiding salt substitutes is important as they may contain potassium chloride, which can also raise potassium levels. Monitoring blood pressure regularly is essential when taking an antihypertensive medication like lisinopril.

5. A nurse is caring for a client receiving corticosteroids. Which of the following should the nurse monitor?

• A. Blood glucose levels
• B. Blood pressure
• C. Serum potassium levels
• D. Both A and B

Correct answer: D

Rationale: When a client is receiving corticosteroids, the nurse should monitor both blood glucose levels and blood pressure. Corticosteroids can elevate blood glucose levels, leading to hyperglycemia, and may cause hypertension. Monitoring these parameters is essential to detect and address any potential adverse effects promptly. While monitoring serum potassium levels is important in some situations, it is not a primary concern when caring for a client receiving corticosteroids. Therefore, choices A and B are the most appropriate options for monitoring in this scenario, making option D the correct answer.
