Extract:
Question 1 of 5
The healthcare provider is using Cognitive-Behavioral methods of pain control and knows that these methods can be expected to do all the following except:
Correct Answer: A
Rationale: Cognitive-Behavioral methods of pain control aim to provide benefit by restoring the client's sense of self-control, helping the client to control symptoms, and encouraging the client to actively participate in their care. However, these methods are not intended to completely relieve all pain. These interventions focus on perception and thought, aiming to influence how one interprets events and bodily sensations.
Therefore, the correct answer is that they cannot completely relieve all pain, as pain relief is often a multifaceted approach that may require additional interventions beyond Cognitive-Behavioral methods.
Choices B, C, and D are correct as Cognitive-Behavioral methods are designed to empower the individual in managing their pain and improving their overall well-being.
Question 2 of 5
The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
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.
Question 3 of 5
Ethics committees typically do not handle which of the following issues?
Correct Answer: A
Rationale: Ethics committees primarily focus on addressing ethical dilemmas in healthcare. Issues like euthanasia, decisions regarding starting or stopping treatment, and the use of feeding tubes for nutritional support involve complex ethical considerations related to patient care and end-of-life decisions, which are commonly deliberated by ethics committees. However, nonpayment of bills is a financial matter and falls outside the typical scope of ethics committees' functions.
Question 4 of 5
A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?
Correct Answer: A
Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.
Question 5 of 5
Why might breast implants interfere with mammography?
Correct Answer: D
Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer.
Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.
