Nclex Exam Cram Practice Questions
1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
- A. serotonin
- B. cortisol
- C. alcohol
- D. narcotics
Correct answer: A
Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
2. While observing a client using crutches for a leg injury, which action would indicate a need for more education by the LPN?
- A. The client places the top padding 1-2 inches below the axilla with a firm grip on the handles.
- B. The client rests the axilla on the top padding and loosely grips the handles with hands.
- C. The client has a slight bend in the elbow when using the handles.
- D. When going down the stairs, the client leads with the injured leg.
Correct answer: B
Rationale: The correct answer is B. Resting the axilla on the top padding can cause nerve damage; instead, the client should place the top padding 1-2 inches below the axilla with a firm grip on the handles for proper support and stability while using crutches. Having a slight bend in the elbow when using the handles (choice C) is a correct technique to ensure proper weight distribution. Leading with the uninjured leg when going down the stairs (choice D) is the correct way to maintain balance and prevent further injury to the injured leg. Therefore, choice B indicates a need for more education to prevent potential nerve damage and ensure safe crutch use.
3. Which of the following tests is commonly performed on newborns with jaundice?
- A. blood urea nitrogen
- B. magnesium
- C. bilirubin
- D. prolactin
Correct answer: C
Rationale: The correct answer is C: bilirubin. A high bilirubin level is found in newborns with hepatic immaturity, leading to jaundice. Testing bilirubin levels is crucial in diagnosing and monitoring jaundice in newborns. Choices A, B, and D (blood urea nitrogen, magnesium, and prolactin) are not commonly performed tests for evaluating jaundice in newborns. Blood urea nitrogen is a measure of kidney function, magnesium levels are usually checked in metabolic disorders, and prolactin is a hormone related to lactation, none of which are directly relevant to assessing jaundice in newborns.
4. The LPN is caring for a client with an NG tube, and the RN administers evening medications through the NG tube. The client asks if he can lie down when the nurse leaves the room. What is the most appropriate response?
- A. You can lie down in 1 hour.
- B. You can lie down in 30 minutes if your NG residual is below 50 mL.
- C. You can lie down in about 30 minutes.
- D. Yes, feel free to lie down.
Correct answer: A
Rationale: After administering medication through an NG tube, the client should remain upright for 30 minutes to ensure proper absorption of the medications. Therefore, the most appropriate response is to advise the client to lie down in 1 hour. Choice B is incorrect because waiting only 30 minutes may not provide sufficient time for the medications to be fully absorbed, as the recommended time is 30 minutes. Choice C is misleading as it incorrectly suggests that lying down in about 30 minutes is acceptable, which could compromise medication effectiveness. Choice D is incorrect as it does not provide accurate information regarding the appropriate timing for lying down after NG tube medication administration, potentially leading to decreased medication absorption.
5. When a 17-year-old client arrives at the clinic suspecting a sexually transmitted infection, what information does the nurse provide concerning informed consent?
- A. She will need to sign an informed consent form.
- B. Her mother or father will need to be contacted for permission to treat her.
- C. A consent form is not needed if the problem is a sexually transmitted infection.
- D. Anyone over the age of 18 years may sign a consent form for her treatment.
Correct answer: A
Rationale: Informed consent is a person's agreement to allow something, such as a treatment, to be performed. A consent form is required even if the problem is a sexually transmitted infection. If the client is a minor, the minor may sign the informed consent form in specific situations, including seeking treatment for a sexually transmitted infection. In this case, the 17-year-old client is seeking examination and treatment for a sexually transmitted infection, so she will need to sign the informed consent form. Contacting her parents for permission is not required in this situation. Choice C is incorrect because a consent form is necessary regardless of the medical issue. Choice D is incorrect because the individual's age is not the determining factor; rather, it is the nature of the medical service being sought that dictates the need for informed consent.
