1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. The client is receiving discharge instructions for a new antihypertensive medication. Which statement by the client indicates a need for further teaching?

• A. I will stop taking the medication if I experience dizziness.
• B. I will monitor my blood pressure regularly.
• C. I will avoid drinking alcohol while taking this medication.
• D. I will rise slowly from a sitting to a standing position.

Correct answer: A

Rationale: The correct answer is A. Stopping antihypertensive medication abruptly can lead to rebound hypertension, which can be dangerous. Clients should never discontinue their medication without consulting their healthcare provider first. Choice B is correct because monitoring blood pressure is essential when taking antihypertensive medication to ensure it stays within the target range. Choice C is correct as alcohol can potentiate the hypotensive effects of antihypertensive medications. Choice D is correct as orthostatic hypotension can occur, so rising slowly helps prevent dizziness and falls. Therefore, choice A is the statement that indicates a need for further teaching.

3. The patient has been diagnosed with diabetes. When admitted, the patient is unkempt and is in need of a bath and foot care. When questioned about hygiene habits, the nurse learns the patient takes a bath once a week and a sponge bath every other day. To provide ultimate care for this patient, which principle should the nurse keep in mind?

• A. Patients who appear unkempt may require guidance on hygiene practices.
• B. Personal preferences can be influenced by health conditions.
• C. The patient's illness may require teaching of new hygiene practices.
• D. Cultural perspectives on cleanliness can vary based on health status.

Correct answer: C

Rationale: In this scenario, the patient's diagnosis of diabetes may necessitate adjustments to their hygiene practices. The nurse should recognize that certain illnesses, like diabetes, can impact hygiene needs. Choice A is incorrect because appearing unkempt does not necessarily indicate a lack of importance on hygiene practices; it may be due to various factors. Choice B is incorrect as health conditions can influence personal preferences and habits. Choice D is incorrect as cultural views on cleanliness are not the primary focus when addressing hygiene practices related to a specific illness.

4. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?

• A. Assess the client for a gag reflex
• B. Measure the pH of the gastric aspirate
• C. Place the end of the NG tube in water to observe for bubbling
• D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water

Correct answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

5. The healthcare provider is preparing a client with deep vein thrombosis (DVT) for a Venous Doppler evaluation. Which of the following would be necessary for preparing the client for this test?

• A. Client should be NPO prior to the test
• B. Client should receive a sedative medication before the test
• C. Discontinue anticoagulant therapy before the test
• D. No special preparation is necessary

Correct answer: D

Rationale: No special preparation is required for a Venous Doppler evaluation. Option A is incorrect because there is no need for the client to be NPO (nothing by mouth) before this test. Option B is incorrect as sedative medication is not typically administered for a Venous Doppler evaluation. Option C is incorrect as discontinuing anticoagulant therapy before the test may not be safe for a client with DVT, as it could increase the risk of developing a blood clot. Therefore, the correct answer is D.
