Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?
- A. mycobacterium tuberculosis
- B. clostridium tetani
- C. staphylococcus aureus
- D. human immunodeficiency virus
Correct Answer: C
Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.

A 20-year-old obese female client is preparing to have gastric bypass surgery for weight loss. She says to the nurse, "I need this surgery because nothing else I have done has helped me to lose weight."? Which response by the nurse is most appropriate?
- A. "If you eat less, you can save some money."?
- B. "Exercise is a healthier way to lose weight."?
- C. "You should try the Atkins diet first."?
- D. "I respect your decision to choose surgery."?
Correct Answer: D
Rationale: The most appropriate response by the nurse is to show respect and empathy towards the client's decision. Option D acknowledges the client's autonomy and decision-making process, fostering a therapeutic relationship. Options A, B, and C are insensitive and unprofessional. Option A implies a financial incentive for weight loss, which can be perceived as disrespectful and trivializing the client's concerns. Option B suggests an alternative method without considering the client's reasons for choosing surgery, potentially invalidating her experiences. Option C recommends a specific diet without addressing the client's concerns or choices, neglecting her autonomy in decision-making.
Nursing care for a client undergoing chemotherapy includes assessment for signs of bone marrow depression. Which finding accounts for some of the symptoms related to bone marrow depression?
- A. erythrocytosis
- B. leukocytosis
- C. polycythemia
- D. thrombocytopenia
Correct Answer: D
Rationale: Thrombocytopenia is an abnormal decrease in the number of platelets, which results in bleeding tendencies. During chemotherapy, bone marrow depression can lead to a reduction in platelet production, causing thrombocytopenia. Erythrocytosis is an abnormal increase in red blood cells, leukocytosis is an increase in white blood cells, and polycythemia is an excess of red blood cells, which is synonymous with erythrocytosis. In the context of chemotherapy, the focus is on the decrease in red and white blood cells, making thrombocytopenia the most relevant finding.
A nurse is taking the health history of an 85-year-old client. Which of the following physical findings is consistent with normal aging?
- A. Increase in subcutaneous fat.
- B. Diminished cough reflex.
- C. Long-term memory loss.
- D. Myopia.
Correct Answer: B
Rationale: The correct answer is 'Diminished cough reflex.' Diminished cough reflex is a physical finding consistent with normal aging in older adults, which can increase the risk of aspiration and atelectasis. An increase in subcutaneous fat actually raises the risk of pressure ulcers. While long-term memory is typically preserved in aging unless affected by dementia, short-term memory often declines. Myopia (near-sightedness) is common in younger individuals, but presbyopia (far-sightedness) is more common with aging. Additionally, individuals with myopia may experience an improvement in vision as they age.
The client is preparing to learn about the effects of isoniazid (INH). Which information is essential for the client to understand?
- A. Isoniazid should be taken with meals to reduce gastrointestinal upset.
- B. Prolonged use of isoniazid may result in dark, concentrated urine.
- C. Taking aluminum hydroxide (Maalox) with isoniazid can enhance the drug's effects.
- D. Consuming alcohol daily can increase the risk of drug-induced hepatitis.
Correct Answer: D
Rationale: It is crucial for the client to understand that consuming alcohol while on isoniazid can increase the risk of drug-induced hepatitis. Hepatic damage can lead to dark, concentrated urine. To minimize gastrointestinal upset, it is recommended to take isoniazid with meals rather than on an empty stomach. Additionally, the client should avoid taking aluminum-containing antacids like aluminum hydroxide with isoniazid, as it can reduce the drug's effectiveness. Choice A is incorrect because isoniazid should not be taken on an empty stomach to help reduce GI upset. Choice B is incorrect, as prolonged use of isoniazid does not typically cause dark, concentrated urine. Choice C is incorrect as taking aluminum hydroxide with isoniazid does not enhance the drug's effects; in fact, it may decrease its effectiveness.
The nurse is assessing the newborn's respirations. Which of these findings would indicate a need for follow-up and further intervention?
- A. irregular respirations
- B. abdominal respirations
- C. shallow respirations
- D. 70 breaths per minute
Correct Answer: D
Rationale: The ideal respiratory rate in a newborn is 30-60 breaths per minute. A respiratory rate of 70 breaths per minute indicates tachypnea and may require intervention. Therefore, a rate of 70 breaths per minute would necessitate follow-up and further intervention. Irregular, abdominal, and shallow respirations are common in newborns and may not necessarily indicate the need for immediate follow-up or intervention.
