1. A nurse is preparing to administer 0.5 mL of oral single-dose liquid medication to a client. Which of the following actions should the nurse take?
- A. Gently shake the container of medication prior to administration
- B. Transfer the medication to a medicine cup
- C. Place the client in a semi-Fowler’s position for medication administration
- D. Verify the dosage by measuring the liquid before administering it
Correct answer: A
Rationale: The correct action for the nurse to take is to gently shake the container of liquid medication before administration. Shaking the container ensures proper mixing of the medication, which is important to maintain uniformity of the dose. Transferring the medication to a medicine cup (choice B) may not be necessary for a small volume like 0.5 mL. Placing the client in a semi-Fowler's position (choice C) is not directly related to administering liquid medication orally. Verifying the dosage by measuring the liquid (choice D) is important but does not address the specific action needed to prepare the medication for administration.
2. For a client with pneumonia, the prescription states, “Oxygen at liters/min per nasal cannula PRN difficult breathing.” Which nursing intervention is effective in preventing oxygen toxicity?
- A. Avoiding the administration of oxygen at high levels for extended periods.
- B. Administering a sedative at bedtime to slow the client’s respiratory rate.
- C. Removing the nasal cannula during the night to prevent oxygen buildup.
- D. Running oxygen through a hydration source prior to administration.
Correct answer: A
Rationale: Choice A is the correct answer because prolonged exposure to high levels of oxygen can lead to oxygen toxicity. Administering oxygen at high levels for extended periods can overwhelm the body's natural defenses against high oxygen levels, causing toxicity. Choices B, C, and D are incorrect. Choice B is unrelated to preventing oxygen toxicity. Choice C is unsafe as removing the nasal cannula can deprive the client of necessary oxygen. Choice D, running oxygen through a hydration source, is not a standard practice for preventing oxygen toxicity.
3. A client who has recently started using a behind-the-ear hearing aid is being cared for by a nurse. Which of the following statements should the nurse identify as an indication that the client understands the use of assistive devices?
- A. “I will be sure to remove my hearing aid before taking a shower.”
- B. “I will keep my hearing aid in at all times, even when sleeping.”
- C. “I will clean my hearing aid with alcohol.”
- D. “I will turn off my hearing aid when not in use.”
Correct answer: A
Rationale: The correct answer is A. It is crucial for the client to remove the hearing aid before showering to prevent damage from moisture. Choice B is incorrect as wearing the hearing aid all the time, including during sleep, is not recommended and can cause discomfort or harm. Choice C is incorrect as alcohol can damage hearing aids; they should be cleaned with a solution recommended by the manufacturer to prevent harm. Choice D is incorrect because hearing aids should not be turned off when not in use; instead, they should be stored properly following the manufacturer's instructions to maintain functionality and battery life.
4. During a nap, a 3-year-old hospitalized child wets the bed. How should the nurse respond?
- A. Ask the child to help with remaking the bed.
- B. Put clean sheets on the bed over a rubber sheet.
- C. Change the child’s clothes without discussing the incident.
- D. Explain that children should call the nurse when they need to go to the bathroom.
Correct answer: C
Rationale: When a 3-year-old hospitalized child wets the bed during a nap, the nurse should respond by changing the child's clothes without discussing the incident. This approach helps to maintain the child's dignity, avoid embarrassment, and reduce anxiety about bedwetting. Asking the child to help remake the bed (Choice A) may not be developmentally appropriate for a 3-year-old and could potentially lead to further distress. Putting clean sheets on the bed over a rubber sheet (Choice B) addresses the aftermath but does not directly address the child's needs and feelings. Explaining that children should call the nurse when they need to go to the bathroom (Choice D) may not be effective in this situation as the child may not have control over bedwetting during sleep.
5. A client with a history of deep vein thrombosis is prescribed enoxaparin. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: Enoxaparin is an anticoagulant that works by preventing blood clots. One of the potential adverse effects of enoxaparin is an increased risk of bleeding due to its anticoagulant properties. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, petechiae, or blood in stool or urine, to ensure timely intervention and prevent complications.
