Nursing Elites

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. A nurse is caring for a patient admitted to the emergency room for an ischemic stroke with marked functional deficits. The physician is considering the use of fibrinolytic therapy with TPA (tissue plasminogen activator). Which history-gathering question would not be important for the nurse to ask?

• A. What time did you first notice symptoms consistently appearing?
• B. Have you been taking any blood thinners such as heparin, lovenox, or warfarin?
• C. Have you had another stroke or head trauma in the previous 3 months?
• D. Have you had any blood transfusions within the previous year?

Correct answer: D

Rationale: The correct answer is 'Have you had any blood transfusions within the previous year?' This question is not relevant in the context of considering fibrinolytic therapy with TPA for an ischemic stroke. Blood transfusions within the previous year do not directly impact the decision to use TPA in the treatment of an acute ischemic stroke. The focus should be on factors such as the time of symptom onset, current medications like blood thinners, and recent history of strokes or head trauma, as these are more directly related to the decision-making process for administering TPA in this emergency situation.

3. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)

• A. Age
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: D

Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.

4. A patient with severe mitral regurgitation and decreased cardiac output is being cared for by a nurse. The nurse assesses the patient for mental status changes. What is the rationale for this intervention?

• A. Decreased cardiac output can cause hypoxia to the brain
• B. Mental status changes may be a side effect of the patient's medication
• C. Mitral regurgitation is a complication associated with some neurological disorders
• D. The patient may be confused about his diagnosis

Correct answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

5. When assessing a patient suspected to have Hepatitis, a nurse notes the patient's eyes are yellow-tinged. Which of the following diagnostic results would further assist in confirming this diagnosis?

• A. Decreased serum Bilirubin
• B. Elevated serum ALT levels
• C. Low RBC and Hemoglobin with increased WBCs
• D. Increased Blood Urea Nitrogen level

Correct answer: B

Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.
