Nursing Elites

1. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.

2. A client with a history of chronic heart failure is admitted with shortness of breath and crackles in the lungs. Which laboratory value should be closely monitored?

• A. Serum creatinine of 2.0 mg/dL
• B. Serum sodium of 135 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Blood glucose of 150 mg/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L should be closely monitored in a client with chronic heart failure as it may indicate hyperkalemia, requiring intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias in patients with heart failure. Serum creatinine (Choice A) is important to monitor for kidney function but is not the priority in this case. Serum sodium (Choice B) and blood glucose (Choice D) levels are not typically the primary focus when assessing a client with heart failure presenting with respiratory symptoms and crackles in the lungs.

3. After placing a stethoscope as seen in the picture, the nurse auscultates S1 and S2 heart sounds. To determine if an S3 heart sound is present, what action should the nurse take first?

• A. Slide the stethoscope across the sternum.
• B. Move the stethoscope to the mitral site.
• C. Listen with the bell at the same location.
• D. Observe the cardiac telemetry monitor.

Correct answer: C

Rationale: The nurse uses the bell of the stethoscope to hear low-pitched sounds such as S3 and S4. To determine if an S3 heart sound is present, the nurse should listen at the same location using the bell first. This allows for the accurate identification of low-pitched sounds. Moving the stethoscope across the sternum (Choice A) or to the mitral site (Choice B) would not be the initial actions to assess for an S3 heart sound. Observing the cardiac telemetry monitor (Choice D) is not relevant for assessing S3 heart sounds, as it does not provide direct auscultation of heart sounds.

4. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. The infant was born two weeks after his due date and is described as a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?

• A. Has your son had any immunizations yet?
• B. Is your son sleepy and difficult to feed?
• C. Are you breastfeeding or bottle-feeding your son?
• D. Were any relatives born with birth defects?

Correct answer: B

Rationale: The correct answer is B. Excessive sleepiness and difficulty feeding can be signs of hypothyroidism in infants. Asking about the infant's sleepiness and feeding pattern is crucial in assessing for hypothyroidism. Choice A is incorrect because immunizations are not directly related to hypothyroidism. Choice C is about feeding method and not specific to hypothyroidism. Choice D is unrelated as it asks about relatives with birth defects, which does not directly assess the infant's condition.

5. When administering ceftriaxone sodium (Rocephin) intravenously to a client, what finding requires the most immediate intervention by the nurse?

• A. Stridor
• B. Nausea
• C. Headache
• D. Pruritus

Correct answer: A

Rationale: The correct answer is A: Stridor. Stridor is a high-pitched sound that indicates airway obstruction. When administering ceftriaxone sodium (Rocephin) intravenously, if the client develops stridor, it is a medical emergency requiring immediate intervention to maintain a patent airway. Nausea, headache, and pruritus are important to assess, but they do not pose an immediate threat to the client's airway and would not require the same level of urgent intervention as stridor.
