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 preparing to administer a dose of ampicillin. Which of the following actions should the nurse take?

• A. Administer it with food
• B. Check for penicillin allergy
• C. Monitor liver function
• D. Administer it intramuscularly

Correct answer: B

Rationale: The correct answer is to 'Check for penicillin allergy.' Before administering ampicillin, it is crucial to assess the patient for any history of penicillin allergy. This is essential to prevent an adverse allergic reaction, as ampicillin belongs to the penicillin class of antibiotics. Administering ampicillin with food (Choice A) is not a standard requirement and does not impact its effectiveness. Monitoring liver function (Choice C) is not directly related to the immediate pre-administration assessment for ampicillin. Administering ampicillin intramuscularly (Choice D) is not typically the route of administration for this antibiotic, as it is usually given intravenously or orally.

3. A nurse is caring for a client who has deep vein thrombosis (DVT) of the left lower extremity. Which of the following actions should the nurse take?

• A. Position the client with the affected extremity higher than the heart
• B. Administer acetaminophen for pain
• C. Massage the affected extremity every 4 hours
• D. Withhold heparin IV infusion

Correct answer: D

Rationale: The correct answer is to withhold heparin IV infusion. The nurse should withhold heparin if there are signs of complications, such as bleeding, or if there are contraindications to continuing anticoagulation therapy. Positioning the client with the affected extremity higher than the heart helps reduce swelling and improve blood flow. Administering acetaminophen for pain management can be appropriate, but it is not the priority in this situation. Massaging the affected extremity can dislodge the clot and lead to serious complications, so it should be avoided.

4. A client who is 38 weeks pregnant with herpes simplex virus is admitted to labor and delivery. What question should the nurse ask?

• A. Do you have any active lesions?
• B. Have your membranes ruptured?
• C. How far apart are your contractions?
• D. Are you positive for beta strep?

Correct answer: A

Rationale: The correct question the nurse should ask the client who is 38 weeks pregnant with herpes simplex virus is 'Do you have any active lesions?' This is crucial because active herpes lesions may necessitate a cesarean delivery to prevent neonatal infection. Choice B, 'Have your membranes ruptured?' is related to assessing for the rupture of membranes, not specific to the client's herpes infection. Choice C, 'How far apart are your contractions?' is related to monitoring labor progress. Choice D, 'Are you positive for beta strep?' is related to group B streptococcus screening, which is important but not the priority in this scenario.

5. A client is prescribed warfarin for anticoagulation. Which of the following laboratory values should the nurse monitor?

• A. PT and INR
• B. Blood glucose levels
• C. Complete blood count (CBC)
• D. Platelet count

Correct answer: A

Rationale: The correct answer is A: PT and INR. Warfarin is an anticoagulant that affects the clotting mechanism by inhibiting vitamin K-dependent clotting factors. The PT (Prothrombin Time) and INR (International Normalized Ratio) are specific laboratory values used to monitor the effectiveness and safety of warfarin therapy. These values help healthcare providers adjust the warfarin dosage to maintain the desired level of anticoagulation. Choices B, C, and D are incorrect because blood glucose levels, complete blood count (CBC), and platelet count are not directly monitored to assess the effects of warfarin therapy.
