1. Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?

A. Lasix (furosemide)
B. Cardizem (diltiazem)
C. Lanoxin (digoxin)
D. Dilantin (phenytoin)

Correct answer: D

Rationale: Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.

2. The nurse is caring for a client awaiting test results on a biopsy. The client is unconscious, and the physician informs the client's spouse that the biopsy came back positive for cancer. The spouse asks the nurse if they will not share this news with the client because they would prefer the client be unaware of the diagnosis. Which of the following responses is most appropriate?

A. "I will have a psychiatrist confirm whether the news will cause negative effects, and if so, I will comply with your request."?
B. "For ethical reasons, I am unable to withhold this information from the client."?
C. "You do not have the option to sign paperwork stating you are accepting the risk of not sharing this with the client."?
D. "You must have a durable power of attorney for healthcare advanced directive in place before I can consider this request."?

Correct answer: B

Rationale: The correct response is, "For ethical reasons, I am unable to withhold this information from the client."? The ethical principle of veracity requires that the nurse is truthful with the client and does not withhold information even if it is requested by the family. Choice A is incorrect because seeking a psychiatrist's confirmation is not necessary to uphold the ethical principle of truth-telling. Choice C is incorrect as implying that signing paperwork overrides the nurse's ethical obligation to be honest with the client is inappropriate. Choice D is also incorrect as a durable power of attorney is not relevant in this situation where the spouse is asking the nurse to withhold information.

3. What is the most common cause of injury from a house fire?

A. Explosion
B. Falls from second-story windows
C. Thermal damage to skin and body surfaces
D. Inhalation injury

Correct answer: D

Rationale: Inhalation injury is the most common cause of injury from a house fire. When a fire occurs, the smoke produced contains harmful gases and particles that can be inhaled, leading to serious respiratory issues. This makes inhalation injury the primary concern during a house fire. Choices A, B, and C are less likely to be the primary cause of injury. While explosions may occur in some cases, inhalation of smoke and toxic fumes is generally the most prevalent danger. Falls from windows and thermal damage to the skin are also significant risks but typically occur after inhalation injuries in the sequence of events during a house fire.

4. The LPN is assisting the client with an NG tube with activities of daily living. Which of these statements would indicate a need for teaching reinforcement?

A. "Since I'm not eating or drinking by mouth, I do not need to brush my teeth as often."?
B. "I should remain sitting up at a 45-degree angle or higher for 30 minutes after a feeding."?
C. "I can clean around the tube with water and mild soap."?
D. "I should avoid using Vaseline around the nostril and tube."?

Correct answer: A

Rationale: The correct answer is, "Since I'm not eating or drinking by mouth, I do not need to brush my teeth as often."? This statement indicates a need for teaching reinforcement because even when an NG tube is in place, the client should still brush their teeth twice daily. Good oral hygiene is essential to reduce the risk of introducing bacteria that may cause an infection. Choice B is incorrect because remaining sitting up at a 45-degree angle or higher for 30 minutes after a feeding is a correct statement regarding NG tube care, promoting proper digestion and reducing the risk of aspiration. Choice C is also incorrect because cleaning around the tube with water and mild soap is an appropriate practice to maintain cleanliness and prevent infection. Choice D is incorrect because advising to avoid using Vaseline around the nostril and tube is a proper instruction to prevent skin breakdown, occlusion of the tube, and potential aspiration of Vaseline into the lungs.

5. When are pressure ulcers most likely to occur?

A. when clients are left in one position in bed for extended periods of time.
B. when clients are underweight.
C. when clients are overweight.
D. only in underweight and overweight clients.

Correct answer: A

Rationale: Pressure ulcers usually occur over bony prominences and are caused by decreased circulation. The client who is left in one position in bed for extended periods of time is more prone to decreased circulation to an area of the body and to acquiring a pressure ulcer. Choices B and C are incorrect as pressure ulcers are not exclusive to underweight or overweight clients. The key factor is prolonged pressure on the skin, not the weight of the client. Therefore, the correct answer is that pressure ulcers are most likely to occur when clients are immobilized in one position for extended periods of time.
