1. When administering a shot of Vitamin K to a 30-day-old infant, which of the following target areas is the most appropriate?

A. Gluteus maximus
B. Gluteus minimus
C. Vastus lateralis
D. Vastus medialis

Correct answer: C

Rationale: When administering medications to infants, it is common to use the vastus lateralis muscle in the thigh for injections. The preferred site is the junction of the upper and middle thirds of the vastus lateralis muscle. This area provides a good muscle mass for the injection and minimizes the risk of hitting nerves or blood vessels. The gluteus maximus and gluteus minimus are not typically used for infant injections due to the risk of injury to the sciatic nerve. The vastus medialis is not as commonly used as the vastus lateralis for infant injections.

2. Which of the following types of dressing changes works as a form of wound debridement?

A. Dry dressing
B. Transparent dressing
C. Composite dressing
D. Wet to dry dressing

Correct answer: D

Rationale: The correct answer is 'Wet to dry dressing.' Wet to dry dressing is a method of wound debridement that involves applying sterile soaked gauze to the wound, allowing it to dry and stick to the wound. When the dressing is removed, it pulls away drainage and debris, aiding in wound debridement. Choice A, 'Dry dressing,' does not actively assist in debridement as it does not collect or remove debris from the wound. Choice B, 'Transparent dressing,' is primarily used for maintaining a moist environment and wound observation, not for debridement. Choice C, 'Composite dressing,' combines multiple layers for different wound care purposes but is not specifically designed for debridement like wet to dry dressing.

3. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

A. The patient is allergic to shellfish.
B. The patient has a pacemaker.
C. The patient suffers from claustrophobia.
D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.

4. The healthcare professional in the Emergency Room is treating a patient suspected to have a Peptic Ulcer. On assessing lab results, the healthcare professional finds that the patient's blood pressure is 95/60, pulse is 110 beats per minute, and the patient reports epigastric pain. What is the PRIORITY intervention?

A. Start a large-bore IV in the patient's arm
B. Ask the patient for a stool sample
C. Prepare to insert an NG Tube
D. Administer intramuscular morphine sulfate as ordered

Correct answer: A

Rationale: The priority intervention in this scenario is to start a large-bore IV in the patient's arm. The patient's low blood pressure (95/60) and elevated pulse rate (110 beats per minute) indicate a potential hemorrhage, requiring immediate fluid resuscitation. Starting a large-bore IV will allow for rapid administration of fluids to stabilize the patient's condition. Asking for a stool sample, preparing to insert an NG tube, or administering morphine sulfate should not take precedence over addressing the hemodynamic instability and potential hemorrhage observed in the patient. These actions may be considered later in the patient's care, but the primary focus should be on addressing the critical issue of fluid replacement and stabilization.

5. Why is it important to genotype HCV before initiating drug therapy?

A. Side effects of nucleotide analogs
B. Measures for improving the appetite
C. Ways to increase activity and exercise
D. Administering alpha-interferon (Intron A)

Correct answer: B

Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.
