Nursing Elites

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. A nurse monitoring a client with a chest tube notes that there is no tidaling of fluid in the water seal chamber. After further assessment, the nurse suspects that the client's lung has reexpanded and notifies the healthcare provider. The healthcare provider verifies with the use of a chest x-ray that the lung has reexpanded, then calls the nurse to ask that the chest tube be removed. Which action should the nurse take first?

• A. Explain the procedure to the client, then remove the chest tube.
• B. Call the nursing supervisor.
• C. Inform the healthcare provider that removal of a chest tube is not a nursing procedure.
• D. Obtain petrolatum-impregnated gauze and ask another nurse to assist in removing the chest tube.

Correct answer: C

Rationale: The correct action for the nurse to take first is to inform the healthcare provider that removal of a chest tube is not a nursing procedure. Actual removal of a chest tube is the duty of a healthcare provider. If the healthcare provider insists that the nurse remove the tube, the nurse must contact the nursing supervisor. Some agencies' policies and procedures may permit an advanced practice nurse to remove a chest tube, but there is no information in the question to indicate that the nurse is an advanced practice nurse. Choice A is incorrect because the nurse should not proceed with removing the chest tube without proper authorization. Choice B is incorrect as calling the nursing supervisor should come after clarifying with the healthcare provider. Choice D is incorrect as the nurse should not begin the process of removing the chest tube without proper guidance and authorization.

3. Which of the following statements by a client indicates adequate preparation for magnetic resonance imaging?

• A. "I should wear earplugs during the test."?
• B. "I should remove my metal jewelry before the test."?
• C. "I should inform the healthcare provider about my pacemaker."?
• D. "I should inform the healthcare provider about my artificial hip."?

Correct answer: A

Rationale: The correct statement is, '"I should wear earplugs during the test,"?' as MRI scanners produce loud noises requiring ear protection. Metal objects, including jewelry, are not allowed inside the MRI room due to safety concerns related to the magnetic field. Choices B, C, and D are incorrect. Choice B is wrong because metal objects, including jewelry, are not permitted in the MRI room. Choices C and D are incorrect as having a pacemaker or an artificial hip raises concerns due to the magnetic field in MRI, requiring special precautions or considerations. It is crucial for individuals with such implants to inform their healthcare provider to assess the risks and determine the appropriate course of action.

4. When placing a Foley catheter in a female client, what is the correct order of steps?

• A. E, A, F, B, C, G, D
• B. A, E, B, F, G, D, C
• C. A, E, F, B, C, G, D
• D. E, A, F, B, C, G, D

Correct answer: D

Rationale: The correct order for placing a Foley catheter in a female client is as follows: E. Place the client in a supine position with flexed knees, A. Prepare the sterile field, F. Place lubricant on the catheter, B. Separate labia with the non-dominant hand, C. Clean the urinary meatus using cleansing solutions and forceps, G. Place the catheter in the meatus with the dominant (sterile) hand, and D. Inflate the catheter balloon. This sequence ensures proper hygiene, patient comfort, and reduces the risk of infection. Incorrect sequences could compromise sterility, cause discomfort, and increase the risk of infection. Therefore, the correct answer is E, A, F, B, C, G, D.

5. What spinal change occurring with pregnancy alters mobility?

• A. Scoliosis.
• B. Kyphosis.
• C. Lordosis.
• D. Ankylosing spondylitis.

Correct answer: C

Rationale: The correct answer is 'Lordosis.' During pregnancy, the enlarging uterus places increased weight on the spine, causing an exaggerated inward curvature known as lordosis. This change alters mobility by shifting the center of gravity forward, leading to a compensatory change in posture. Scoliosis (choice A) is a sideways curvature of the spine, not typically associated with pregnancy. Kyphosis (choice B) is an exaggerated outward curvature of the spine, while ankylosing spondylitis (choice D) is a chronic inflammatory condition affecting the spine, neither of which are directly related to the spinal changes seen in pregnancy.
