A client with human immunodeficiency virus (HIV) undergoes intradermal anergy testing using Candida and mumps antigen. During the 3 days following the tests, there is no induration or evidence of reaction at the intradermal injection sites. The most accurate conclusion the nurse can make is:
- A. The client has no previous exposure to the antigens injected
- B. The results demonstrate the client has antibodies to the antigens
- C. The client is immunodeficient and won’t have a skin response
- D. The client isn’t allergic to the antigens and therefore doesn’t react
Correct Answer: C
Rationale: The correct answer is C because a lack of response to intradermal anergy testing suggests an inability to mount a normal delayed-type hypersensitivity response, indicating immunodeficiency. This could be due to conditions such as HIV, which impairs cell-mediated immunity.
Choice A is incorrect because absence of reaction does not necessarily indicate lack of previous exposure to antigens.
Choice B is incorrect as the absence of response doesn't confirm the presence of antibodies.
Choice D is incorrect because anergy testing is not used to assess allergy, but rather to evaluate cell-mediated immunity.

A client has possible malignancy of the colon, and surgery is scheduled. The rationale for administering Neomycin preoperatively is to:
- A. Prevent infection postoperatively
- B. Eliminate the need for preoperative enemas
- C. Decreased and retard the growth of normal bacteria in the intestines
- D. Treat cancer of the colon
Correct Answer: C
Rationale: The correct answer is C because Neomycin is given preoperatively to decrease and retard the growth of normal bacteria in the intestines. This helps reduce the risk of infection during surgery by minimizing the number of bacteria present in the colon. Options A, B, and D are incorrect because Neomycin is not given to prevent infection postoperatively, eliminate the need for preoperative enemas, or treat cancer of the colon. The main purpose of administering Neomycin in this scenario is to create a sterile surgical field by reducing the normal flora in the intestines.
The nurse understands that labyrinthitis is treated primarily with which of the ff. drug categories?
- A. Antihistamines
- B. Anti-inflammatories
- C. Antispasmotics
- D. Antiemetics
Correct Answer: A
Rationale: The correct answer is A: Antihistamines. Labyrinthitis is an inner ear condition often caused by inflammation or infection. Antihistamines help reduce symptoms like vertigo and dizziness by decreasing inflammation and fluid buildup in the inner ear. Anti-inflammatories (choice B) may help with inflammation but are not as effective for inner ear conditions. Antispasmotics (choice C) are not typically used for treating labyrinthitis. Antiemetics (choice D) are used to control nausea and vomiting, which can be symptoms of labyrinthitis but do not address the underlying cause.
. A client is diagnosed with the syndrome of inappropriate antidiuretic hormone (SIADH). The nurse should anticipate which laboratory test result?
- A. Decreased serum sodium level
- B. Increased blood urea nitrogen
- C. Decreased serum creatinine level (BUN) level
- D. Increased hematocrit
Correct Answer: A
Rationale: The correct answer is A: Decreased serum sodium level. In SIADH, there is an excessive release of ADH, causing water retention and dilution of sodium in the blood. This leads to hyponatremia. B: Increased blood urea nitrogen and C: Decreased serum creatinine level are not typically associated with SIADH. D: Increased hematocrit is not a typical finding in SIADH, as it is more related to dehydration. Therefore, the most anticipated laboratory test result in a client with SIADH is a decreased serum sodium level due to dilutional hyponatremia.
A new nurse is working in a unit that uses interdisciplinary collaboration. Which action will the nurse take?
- A. Act as a leader of the health care team.
- B. Develop good communication skills.
- C. Work solely with nurses.
- D. Avoid conflict.
Correct Answer: B
Rationale: The correct answer is B: Develop good communication skills. In interdisciplinary collaboration, effective communication is essential for teamwork. By developing good communication skills, the nurse can effectively interact with other healthcare professionals to provide holistic care. Choice A is incorrect as the nurse should collaborate as part of a team, not necessarily be the leader. Choice C is incorrect as interdisciplinary collaboration involves working with professionals from various disciplines. Choice D is incorrect as conflict resolution is an important aspect of effective collaboration.
The spouse of a client with gastric cancer expresses concern that the couple’s children may develop this type of cancer when they’re older. When reviewing risk factors for gastric cancer with the client and family, the nurse explains that a certain blood type increases the risk by 10%. The nurse is referring to:
- A. Type A
- B. Type AB
- C. Type B
- D. Type O
Correct Answer: A
Rationale: The correct answer is A: Type A. Individuals with blood type A have a slightly higher risk of developing gastric cancer compared to other blood types. This is due to the presence of certain antigens associated with Type A blood that may increase susceptibility to gastric cancer. In this case, the nurse mentions a 10% increased risk for individuals with Type A blood, which aligns with the known epidemiological data.
Choice B: Type AB is incorrect because individuals with Type AB blood do not have a known increased risk of gastric cancer.
Choice C: Type B is incorrect because individuals with Type B blood do not have a known increased risk of gastric cancer.
Choice D: Type O is incorrect because individuals with Type O blood actually have a slightly lower risk of developing gastric cancer compared to individuals with Type A blood.
