Exam Cram NCLEX RN Practice Questions - Nurselytic

Correct Answer: B

Rationale: Starting prophylactic AZT treatment is the most critical intervention in this scenario. Azidothymidine (AZT) is an antiretroviral medication used to prevent and treat HIV/AIDS by reducing the replication of the virus. Post-exposure prophylaxis (PEP) for HIV involves taking medication to suppress the virus and prevent infection after exposure. PEP should be initiated within 72 hours of potential HIV exposure to be effective. Seeking treatment quickly is crucial to enhance its effectiveness. Seeing a social worker (
Choice
A) may be helpful for emotional support but is not the immediate priority. Pentamidine treatment (
Choice
C) is not indicated for post-exposure prophylaxis for HIV. Seeking counseling (
Choice
D) is important for the nursing student's emotional well-being but does not address the urgent need for post-exposure prophylaxis to prevent HIV transmission.

Correct Answer: B

Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.

Correct Answer: B

Rationale: The correct answer is the teenager who suffered singed facial hair while camping. This client is in the greatest danger with a potential risk of respiratory distress. Singed facial hair indicates exposure to heat or fire in close range, which could have caused serious damage to the interior of the lungs. It's crucial to prioritize this client as the interior lining of the lungs has no nerve fibers, so swelling may not be immediately noticeable. The other choices, while concerning, do not present an immediate life-threatening situation. The infant's condition may be serious but does not pose an immediate danger of respiratory distress. The elderly client's symptoms could indicate gastrointestinal issues, which are important but not as urgent as potential respiratory compromise. The middle-aged client's pain behind the right scapula, while uncomfortable, does not indicate an acute life-threatening condition requiring immediate attention.

Correct Answer: C

Rationale:
To convert ounces to cc, we know that there are 30 cc in 1 ounce.
Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer.

Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.

Correct Answer: B

Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.
