Adult Health 2 Exam 1
1. What is the primary function of neutrophils?
- A. Heparin secretion
- B. Transport oxygen
- C. Phagocytotic action
- D. Antibody formation
Correct answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
2. Which client assessment falls within the scope of practice for the practical nurse?
- A. An agitated client with bilateral wrist restraints
- B. New admission of a client with deep vein thrombosis
- C. Return of a post-anesthesia client following a colon resection
- D. Transfer of a client with sepsis from a long-term care facility
Correct answer: B
Rationale: The correct answer is B because assessing a new deep vein thrombosis (DVT) patient is within the scope of practical nursing. It involves monitoring and supporting the circulatory system health, which is a common responsibility for practical nurses. Choices A, C, and D involve scenarios that are typically beyond the initial assessment and care provided by practical nurses. An agitated client with bilateral wrist restraints may require immediate intervention by higher-level healthcare providers due to safety concerns and potential underlying issues. The return of a post-anesthesia client following a colon resection and the transfer of a client with sepsis involve more specialized care that goes beyond the typical responsibilities of a practical nurse, often requiring interventions from registered nurses or physicians.
3. During a routine prenatal visit, a nurse measures a client’s fundal height. The client is 26 weeks pregnant. What should the fundal height be?
- A. Approximately 26 cm
- B. Between 24 to 28 cm
- C. Above the umbilicus by two finger widths
- D. Below the xiphoid process
Correct answer: B
Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.
4. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?
- A. Alkalosis
- B. Acidosis
- C. Normal serum pH
- D. Incompatible with life
Correct answer: C
Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
5. The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?
- A. The solution's rate is too rapid
- B. The client has phlebitis
- C. The infusion site is infected
- D. The infusion is infiltrated
Correct answer: D
Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.
