1. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?
- A. normal
- B. elevated
- C. low
- D. unrelated to the pH
Correct answer: B
Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.
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. Which of the following viruses is most likely to be acquired through casual contact with an infected individual?
- A. influenza virus
- B. herpes virus
- C. cytomegalovirus (CMV)
- D. human immunodeficiency virus (HIV)
Correct answer: A
Rationale: The correct answer is influenza virus. Influenza virus is most likely to be acquired through casual contact with an infected individual as it is transmitted through respiratory droplets. Herpes virus is primarily transmitted by direct contact, such as skin-to-skin contact, making it less likely to be acquired through casual contact. HIV is mainly transmitted through blood and body fluids like semen and vaginal fluids, not through casual contact. Cytomegalovirus (CMV) is an opportunistic infection commonly affecting immunocompromised individuals and is usually transmitted through close personal contact, not casual contact.
4. Teaching about the need to avoid foods high in potassium is most important for which client?
- A. a client receiving diuretic therapy
- B. a client with an ileostomy
- C. a client with metabolic alkalosis
- D. a client with renal disease
Correct answer: D
Rationale: Clients with renal disease are predisposed to hyperkalemia and should avoid foods high in potassium. High potassium levels can further burden the kidneys and worsen the condition. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk for hypokalemia, which is low potassium levels. Therefore, these clients should actually be encouraged to eat foods high in potassium to maintain adequate levels and prevent complications associated with hypokalemia.
5. Which of the following injuries, presented by a client entering the Emergency Department, is the highest priority?
- A. open leg fracture
- B. open head injury
- C. stab wound to the chest
- D. traumatic amputation of a thumb
Correct answer: C
Rationale: A stab wound to the chest is the highest priority injury. This type of injury can lead to lung collapse and mediastinal shift, potentially resulting in death if left untreated. Treating an obstructed airway or a chest wound takes precedence over addressing hemorrhage. The principle of ABC (airway, breathing, and circulation) guides care decisions in prioritizing life-threatening situations. An open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate threat to life compared to a stab wound to the chest. An open leg fracture may lead to significant blood loss but is not immediately life-threatening. An open head injury requires assessment and intervention but does not impact airway, breathing, or circulation directly. Traumatic amputation of a thumb is a serious injury but can be managed after addressing more life-threatening conditions.
