Exam Cram NCLEX RN Practice Questions - Nurselytic

Correct Answer: C

Rationale: When blood pressure measured in the arm is significantly elevated, especially in adolescents and young adults, it is crucial to compare it with thigh pressure to assess for coarctation of the aorta. The popliteal artery, not the femoral artery, should be auscultated for the thigh pressure reading as the femoral artery is closer to the placement of the blood pressure cuff. Generally, thigh pressure is higher than arm pressure; however, if there is coarctation of the artery, arm pressures can be higher than thigh pressures. The preferred position for measuring thigh pressure is the prone position, not supine, with the knee slightly bent to facilitate accurate readings.

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: C

Rationale: The correct order of the layers of skin from outermost to innermost is the epidermis, dermis, and then the hypodermis. The epidermis is the outermost layer of the skin, followed by the dermis, which is the middle layer containing connective tissue, hair follicles, and sweat glands. The hypodermis, also known as the subcutaneous tissue, lies beneath the dermis and consists of fat and connective tissue.
Choice A is incorrect as it lists the layers in the reverse order.
Choice B is incorrect as it reverses the order of the layers.
Choice D is incorrect as there is a correct answer among the choices.

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: 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.
