Nursing Elites

1. When giving an intramuscular injection to an infant, which of the following sites is preferred?

• A. Ventrogluteal region
• B. Deltoid
• C. Vastus lateralis
• D. Dorsogluteal region

Correct answer: C

Rationale: The correct answer is the Vastus lateralis when giving an intramuscular injection to an infant. The Vastus lateralis muscle, located in the thigh, is the preferred site for infants as it has a larger muscle mass and is well-developed, making it suitable for injections. The Ventrogluteal region and Dorsogluteal region are not recommended for infants due to their smaller muscle mass and potential risk of damaging nearby structures. The Deltoid muscle is typically used for older children and adults, not infants.

2. A patient has fallen off a bicycle and fractured the head of the proximal fibula. A cast was placed on the patient's lower extremity. Which of the following is the most probable result of the fall?

• A. Peroneal nerve injury
• B. Tibial nerve injury
• C. Sciatic nerve injury
• D. Femoral nerve injury

Correct answer: A

Rationale: The correct answer is peroneal nerve injury. The head of the proximal fibula is in close proximity to the peroneal nerve, making it susceptible to injury when there is a fracture. The peroneal nerve runs along the fibula and can be affected by trauma to this area. Choice B, tibial nerve injury, is incorrect as the fracture site is closer to the peroneal nerve, not the tibial nerve. Choice C, sciatic nerve injury, is incorrect as the injury is more localized to the fibular head area where the peroneal nerve is affected. Choice D, femoral nerve injury, is incorrect as the femoral nerve is not immediately adjacent to the proximal fibula and is not typically affected by this type of injury.

3. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:

• A. Manage peripheral edema
• B. Improve right ventricular function
• C. Increase pulmonary pressure
• D. Constrict the pulmonary vessels

Correct answer: B

Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.

4. A female client complains to the nurse at the health department that she has fatigue, shortness of breath, and lightheadedness. Her history reveals no significant medical problems. She states that she is always on a fad diet without any vitamin supplements. Which tests should the nurse expect the client to have first?

• A. peptic ulcer studies
• B. complete blood count, including hematocrit and hemoglobin
• C. genetic testing
• D. hemoglobin electrophoresis

Correct answer: B

Rationale: The correct answer is to perform a complete blood count, including hematocrit and hemoglobin, as the initial tests to assess the client's symptoms related to fatigue, shortness of breath, and lightheadedness. These symptoms can be indicative of anemia, which can be caused by nutritional deficiencies due to fad dieting without vitamin supplements. Peptic ulcer studies, genetic testing, and hemoglobin electrophoresis are not the most appropriate initial tests for the client's presenting symptoms and history. Peptic ulcer studies are not relevant to the client's symptoms. Genetic testing is not indicated based on the client's presentation and history. Hemoglobin electrophoresis is used to diagnose specific types of anemia and is not the first-line test in this scenario. Further testing decisions should be based on the results of the initial tests, the client's history, and other relevant factors.

5. Assessment of the client with an arteriovenous fistula for hemodialysis should include:

• A. inspection for visible pulsations.
• B. palpation of thrill.
• C. percussion for dullness.
• D. auscultation of blood pressure.

Correct answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.
