To auscultate for a carotid bruit, the nurse places the stethoscope at what location (Select the correct location on the image. To change, click on a new location.)
A
B
C
D
The Correct Answer is A
A. The neck is the correct location for auscultating a carotid bruit. A carotid bruit is an abnormal sound heard over the carotid artery in the neck, typically indicative of turbulent blood flow due to a narrowing or blockage in the artery.
B. Auscultating the femoral region would not yield information about carotid bruits. The femoral region pertains to the upper thigh area and is not anatomically related to the carotid artery.
C. The cubital fossa is the inner elbow region and is not associated with auscultation for carotid bruits. It is typically used for auscultation of blood pressure using the brachial artery.
D. The navel (belly button) is not a relevant location for auscultation for carotid bruits. It is far from the carotid arteries and would not provide any meaningful information about carotid artery sounds.

Correct Answer is []
Explanation
Hypocalcemia:
- Condition: Hypocalcemia is a condition characterized by low levels of calcium in the blood. In newborns and infants, this can occur due to inadequate intake or absorption of calcium, and it can manifest as seizures.
- Rationale: The infant was fed cow's milk, which is not recommended for infants under one year old and can interfere with calcium absorption, possibly leading to hypocalcemia. Seizures can be a symptom of severe hypocalcemia.
Actions to Take:
1. Administer oral calcium:
- Rationale: Direct administration of calcium helps to quickly elevate calcium levels in the blood, addressing the immediate cause of the seizures.
2. Educate the mother on nutrition needs:
- Rationale: It's important to educate the mother on the appropriate nutritional needs for an
infant, emphasizing the importance of breastfeeding or formula feeding instead of cow's milk, to prevent recurrence.
Parameters to Monitor:
1. Electrocardiogram:
- Rationale: Monitoring the ECG is crucial as hypocalcemia can cause cardiac arrhythmias, and the ECG can provide real-time information about the infant's cardiac status.
2. Oxygen saturation:
- Rationale: Monitoring oxygen saturation ensures that the infant maintains adequate oxygenation, especially after a seizure and during recovery, to detect any respiratory complications early.
Correct Answer is D
Explanation
A. Verify the prothrombin time (PT).
While it is important to verify coagulation status in patients with atrial fibrillation to ensure they are not at high risk for bleeding, this is not the most critical step immediately prior to
cardioversion. The PT is more relevant if anticoagulation therapy is being managed.
B. Administer prescribed sedative.
Administering a sedative is important for patient comfort during the procedure, but it is not the most critical step that directly affects the success and safety of the cardioversion itself.
C. Select a monitor lead with a tall R wave.
Selecting a monitor lead with a tall R wave helps in accurately synchronizing the cardioversion shock with the R wave, but this is secondary to activating the synchronization mode which is critical to avoid delivering a shock during the vulnerable period of the cardiac cycle.
D. Activate the synchronization mode.
This is the correct answer. The most important action before deploying the current for cardioversion is to ensure the defibrillator is in synchronization mode. Synchronization ensures that the electrical shock is delivered at the correct time during the cardiac cycle, specifically on the R wave of the QRS complex, to avoid inducing ventricular fibrillation. This is crucial for
patient safety.
