1. A nurse is teaching a client newly diagnosed with Emphysema about the disease process. Which of the following statements best explains the problems associated with emphysema and could be adapted for use in the nurse's discussion with the client?
- A. Hyperactivity of the medium-sized bronchi caused by an inflammatory response leads to wheezing and tightness in the chest.
- B. Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.
- C. Vasodilation, congestion, and mucosal edema cause a chronic cough and sputum production.
- D. Chloride is not being transported properly, producing excess absorption of water and sodium, and thick viscous mucus
Correct answer: B
Rationale: The correct answer is: 'Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.' Emphysema is a breakdown of the elastin and fiber network of the alveoli where the alveoli enlarge or the walls are destroyed. This alveolar destruction leads to the formation of larger-than-normal air spaces. Emphysema is one of a group of pulmonary diseases of a chronic nature characterized by increased resistance to airflow; the entity is part of chronic obstructive pulmonary disease (COPD). Choice A is incorrect because emphysema is not primarily characterized by hyperactivity of the medium-sized bronchi causing wheezing and tightness in the chest. Choice C is incorrect because vasodilation, congestion, and mucosal edema are not the primary mechanisms involved in emphysema, and they do not directly lead to chronic cough and sputum production. Choice D is incorrect because emphysema is not related to chloride transport issues and thick viscous mucus production.
2. During the admission assessment for a client undergoing breast augmentation, which information should the nurse prioritize reporting to the surgeon before surgery?
- A. The client is concerned about who will care for her two children while she recovers.
- B. The client has a history of postoperative dehiscence after a previous C-section.
- C. The client's statement that her last menstrual period was 8 weeks prior.
- D. The client's concerns over pain control postoperatively.
Correct answer: C
Rationale: The most important information for the nurse to report to the surgeon before surgery is the client's statement that her last menstrual period was 8 weeks prior. This information is crucial as the client may be pregnant, and a pregnancy test will need to be completed before administering any anesthetic agents. Reporting this detail ensures patient safety and prevents potential risks associated with anesthesia. Choices A, B, and D are important aspects of care but do not take precedence over the need to rule out pregnancy before surgery.
3. A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:
- A. increased therapeutic effects of Drug A.
- B. increased adverse effects of Drug B.
- C. decreased therapeutic effects of Drug A.
- D. decreased therapeutic effects of Drug B.
Correct answer: C
Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.
4. The nurse is preparing for a dressing change on a full thickness burn to the flank area. The orders include irrigating the wound with each dressing change. To irrigate the wound, what will the nurse use?
- A. Sterile saline
- B. Distilled water
- C. Betadine scrub
- D. Tap water
Correct answer: A
Rationale: When irrigating a wound, especially in the case of a full-thickness burn, it is crucial to use a solution that is gentle and non-irritating to the tissues. Sterile saline is the preferred choice for wound irrigation as it is isotonic and does not cause additional damage to the already compromised tissue. Distilled water lacks the electrolytes present in saline, Betadine scrub is not used for irrigation due to its potential to be cytotoxic, and tap water may introduce contaminants and microorganisms to the wound.
5. Which of the following medications is not classified as a neuromuscular blocker?
- A. Anectine
- B. Pavulon
- C. Pitressin
- D. Mivacron
Correct answer: C
Rationale: The correct answer is Pitressin. Pitressin is a hormone replacement medication and is not classified as a neuromuscular blocker. Choices A, B, and D (Anectine, Pavulon, Mivacron) are neuromuscular blockers used during anesthesia to induce muscle relaxation for various procedures. Anectine is also known as succinylcholine, Pavulon is rocuronium, and Mivacron is mivacurium. These medications act on the neuromuscular junction to block the transmission of nerve impulses, leading to muscle relaxation.
