Correct Answer: C

Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.

Correct Answer: A

Rationale: When an elderly client with cancer is receiving NSAID therapy, monitoring BUN (blood urea nitrogen) and creatinine levels is crucial. NSAIDs can cause renal toxicity, especially in the elderly. BUN and creatinine levels help assess renal function and detect early signs of renal impairment. Monitoring creatinine alone (Choice B) is not sufficient as BUN provides complementary information about renal function. Monitoring hemoglobin (Hgb) and hematocrit (Hct) (Choice C) is important for assessing anemia but not specific to NSAID therapy in the elderly. CFT (Choice D) is not a standard abbreviation in this context, and monitoring coagulation function is not directly related to NSAID therapy in this scenario.

Correct Answer: D

Rationale: Compulsive behavior is not a clinical sign typically associated with congestive heart failure (CHF). CHF commonly presents with symptoms such as increased body weight due to fluid retention, elevated heart rate as the heart works harder to pump blood effectively, and lower extremity edema caused by fluid buildup. While behavioral changes can occur in response to illness, compulsive behavior is not a typical indicator of CHF. Choices A, B, and C are more commonly linked to CHF and should be monitored in patients with this condition.

Correct Answer: C

Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.

Correct Answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).
