Exam Cram NCLEX RN Practice Questions
1. A leukemia patient has a relative who wants to donate blood for transfusion. Which of the following donor medical conditions would prevent this?
- A. A history of hepatitis C five years previously
- B. Cholecystitis requiring cholecystectomy one year previously
- C. Asymptomatic diverticulosis
- D. Crohn's disease in remission
Correct answer: A
Rationale: A history of hepatitis C five years previously would prevent a donor from donating blood for transfusion. Hepatitis C is a viral infection transmitted through bodily fluids, such as blood, causing inflammation of the liver. Patients with hepatitis C may not donate blood for transfusion due to the high risk of infection in the recipient. Cholecystitis requiring cholecystectomy one year previously, asymptomatic diverticulosis, and Crohn's disease in remission are not contraindications for blood donation as they do not pose a risk of transmitting infections to the recipient.
2. How many cc are there in 25 ounces?
- A. 250
- B. 500
- C. 750
- D. 1000
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.
3. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?
- A. The admission orders are written.
- B. A blood culture is drawn.
- C. A complete blood count with differential is drawn.
- D. The parents arrive.
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.
4. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)
- A. HCV
- B. HPV
- C. HIV
- D. HBV
Correct answer: A
Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.
5. The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?
- A. Slope of the earpieces should point forward toward the examiner's nose.
- B. It blocks out extraneous room noise but does not magnify sound.
- C. The tubing length should be 14 to 18 inches to prevent sound distortion.
- D. Both fit and quality of the stethoscope are important.
Correct answer: B
Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.
