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.

During the initial newborn assessment, the nurse finds that a newborn's heart rate is irregular. Which intervention should the nurse implement?
- A. Notify the pediatrician immediately.
- B. Teach the parents about congenital heart defects.
- C. Document the finding in the infant's record.
- D. Apply oxygen via nasal cannula at 3 L/min.
Correct Answer: C
Rationale: The correct intervention when a nurse finds an irregular heart rate in a newborn is to document the finding in the infant's record. An irregular heart rate is a common occurrence in newborns and does not necessarily require immediate medical intervention. Notifying the pediatrician immediately is unnecessary unless there are other concerning symptoms. Teaching the parents about congenital heart defects is not the priority in this situation. Applying oxygen via nasal cannula at 3 L/min is not indicated for an irregular heart rate without further assessment or medical indication.
While a child is hospitalized with acute glomerulonephritis, the parents ask why blood pressure readings are taken so often. Which response by the nurse is most accurate?
- A. Elevated blood pressure must be anticipated and identified quickly
- B. Frequent monitoring helps ensure the medication is effective
- C. It is standard protocol for all hospitalized children
- D. We need to monitor for any potential kidney damage
Correct Answer: A
Rationale: The correct answer is A: 'Elevated blood pressure must be anticipated and identified quickly.' Acute glomerulonephritis can lead to significant hypertension, making it crucial to monitor blood pressure frequently to promptly identify any elevation. Choice B is incorrect because while monitoring can help assess medication effectiveness, the primary reason for frequent blood pressure checks in this case is to detect elevated blood pressure. Choice C is incorrect as not all hospitalized children require such frequent blood pressure monitoring. Choice D is incorrect as the primary reason for monitoring blood pressure is to detect hypertension, rather than solely focusing on potential kidney damage.
A client with chronic heart failure is admitted with shortness of breath and a new onset of confusion. Which intervention should the nurse implement first?
- A. Obtain a neurological assessment.
- B. Administer oxygen therapy.
- C. Monitor the client's urine output.
- D. Obtain an electrocardiogram (ECG).
Correct Answer: A
Rationale: The correct answer is to obtain a neurological assessment. In a client with chronic heart failure presenting with confusion, the priority is to assess neurological status to rule out potential causes such as hypoxia or other complications. Administering oxygen therapy (Choice B) is important but assessing the neurological status takes precedence in this scenario. Monitoring urine output (Choice C) and obtaining an ECG (Choice D) may be necessary but are not the initial priority when a client presents with confusion alongside shortness of breath.
A client is admitted for type 2 diabetes mellitus (DM) and chronic kidney disease (CKD). Which breakfast selection by the client indicates effective learning?
- A. Scrambled eggs, bacon, one slice of whole wheat toast with butter and jam.
- B. Oatmeal with butter, artificial sweetener, and strawberries, and 6 ounces of coffee.
- C. Banana pancake with maple syrup, sausage links, half grapefruit, and low-fat milk.
- D. Orange juice, yogurt with berries, cold cereal with milk, bran muffin with margarine.
Correct Answer: B
Rationale: The correct answer is B. Oatmeal with butter, artificial sweetener, and strawberries is a suitable choice for a client with type 2 diabetes mellitus and chronic kidney disease as it provides a balanced meal that helps manage blood sugar levels and kidney function. Choice A contains high saturated fats and added sugars from bacon, butter, and jam, which are not ideal for this client. Choice C includes high sugar content from maple syrup and pancake, which can negatively impact blood sugar levels. Choice D contains high sugar content from orange juice and cold cereal, which can lead to blood sugar spikes, not suitable for a client with diabetes and CKD.
A client with a history of angina pectoris is prescribed sublingual nitroglycerin. Which client statement indicates that further teaching is needed?
- A. 'I should take the nitroglycerin with a full glass of water.'
- B. 'I should take the nitroglycerin as soon as I feel chest pain.'
- C. 'I can take up to three doses of nitroglycerin if needed.'
- D. 'I should call 911 if my chest pain does not improve after the first dose.'
Correct Answer: A
Rationale: The correct answer is A. Sublingual nitroglycerin should not be taken with water, as it needs to dissolve under the tongue to be effective. Option B is correct as the client should take nitroglycerin as soon as they feel chest pain. Option C is correct as up to three doses can be taken if needed. Option D is correct as the client should seek emergency help if chest pain does not improve after the first dose.
