A nurse is teaching a client who has hepatitis A about preventing transmission of the virus. Which of the following strategies should the nurse include in the teaching?
- A. Practice effective hand hygiene.
- B. Limit physical activity.
- C. Use antiseptic mouthwash.
- D. Avoid drinking water.
Correct Answer: A
Rationale: The correct answer is A: Practice effective hand hygiene. This is crucial in preventing transmission of hepatitis A, which is primarily spread through fecal-oral route. Handwashing with soap and water can remove the virus from hands. Limiting physical activity (B) and using antiseptic mouthwash (C) are not effective in preventing transmission. Avoiding drinking water (D) is not necessary unless the water source is contaminated.

A nurse in an emergency room is caring for a client who sustained partial-thickness burns to both lower legs, chest, face, and both forearms. Which of the following is the priority action the nurse should take?
- A. Inspect the mouth for signs of inhalation injuries
- B. Administer pain medication
- C. Place the client on oxygen therapy
- D. Start an intravenous line
Correct Answer: A
Rationale: The correct answer is A: Inspect the mouth for signs of inhalation injuries. This is the priority action because inhalation injuries can be life-threatening and must be assessed immediately in burn patients. Burns to the face and chest increase the risk of inhalation injuries due to the proximity to the airway. Administering pain medication, placing the client on oxygen therapy, and starting an IV line are important interventions but inspecting the mouth for signs of inhalation injuries takes precedence in this situation to ensure the client's airway is not compromised.
A nurse is teaching a class about preventive care to clients who are at risk for acquiring viral hepatitis. Which of the following information should the nurse include in the presentation?
- A. Avoid foods prepared with tap water.
- B. Vaccination against hepatitis B and C is recommended.
- C. Wash hands thoroughly after using the restroom.
- D. Food should be prepared with purified water.
Correct Answer: D
Rationale: The correct answer is D: Food should be prepared with purified water. Hepatitis A virus can be spread through contaminated water or food. Using purified water for food preparation can help prevent the transmission of the virus. Choice A is incorrect because avoiding foods prepared with tap water alone may not be sufficient to prevent hepatitis. Choice B is incorrect as there is no vaccination available for hepatitis C. Choice C is important for general hygiene but may not specifically prevent hepatitis transmission.
A nurse is admitting a client who has a serum calcium level of 12.3 mg/dL and initiates cardiac monitoring. Which of the following findings should the nurse expect during the initial assessment?
- A. Lethargy
- B. Hypertension
- C. Muscle spasms
- D. Severe agitation
Correct Answer: A
Rationale: The correct answer is A: Lethargy. A serum calcium level of 12.3 mg/dL indicates hypercalcemia. In hypercalcemia, calcium affects the central nervous system, leading to lethargy, weakness, and confusion. Lethargy is a common early symptom of hypercalcemia. Hypertension is not typically associated with hypercalcemia. Muscle spasms are more common in hypocalcemia. Severe agitation is not a typical manifestation of hypercalcemia.
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?
- A. Abnormally prominent U wave
- B. Tachycardia
- C. Flattened P wave
- D. Prolonged PR interval
Correct Answer: A
Rationale: The correct answer is A: Abnormally prominent U wave. In hypokalemia, low potassium levels can lead to U wave prominence on an EKG. The U wave becomes more visible and prominent due to delayed repolarization of the Purkinje fibers. This is a classic EKG finding in hypokalemia. Tachycardia (choice B) is a non-specific finding and can be caused by various conditions. Flattened P wave (choice C) is seen in hyperkalemia, not hypokalemia. Prolonged PR interval (choice D) is more indicative of first-degree heart block or other conduction abnormalities, not specifically hypokalemia.
A nurse is caring for a client with a tracheostomy. The client's partner has been taught to perform suctioning. Which of the following actions by the partner should indicate to the nurse a readiness for the client's discharge?
- A. Performing the procedure independently
- B. Preparing the suction equipment but needing assistance
- C. Demonstrating knowledge of the tracheostomy care instructions
- D. Asking for assistance with the suctioning procedure
Correct Answer: A
Rationale: The correct answer is A. Performing the procedure independently indicates readiness for discharge as it shows the partner has mastered the skill and can provide proper care without supervision. Choice B indicates the partner still needs assistance, choice C shows knowledge but not necessarily competency, and choice D suggests continued reliance on the nurse.
