The nurse is caring for a client with heart failure. Which of these prescribed medications places the client at risk for cardiogenic shock?
Digoxin.
Hydrochlorothiazide.
Nadolol.
Captopril.
The Correct Answer is C
A. Digoxin.
Digoxin is a cardiac glycoside that helps increase the force of myocardial contraction and is generally used to treat heart failure. It does not typically pose a significant risk for cardiogenic shock.
B. Hydrochlorothiazide.
Hydrochlorothiazide is a diuretic used to manage fluid retention in heart failure. It can cause electrolyte imbalances but is not directly linked to causing cardiogenic shock.
C. Nadolol.
Nadolol is a beta-blocker, which can reduce the heart rate and the strength of heart contractions. In a client with severe heart failure, excessive beta-blockade can lead to a significant decrease in cardiac output, increasing the risk for cardiogenic shock.
D. Captopril.
Captopril is an ACE inhibitor that helps manage heart failure by reducing afterload and preload.
While it can cause hypotension, it is not typically associated with a direct risk of cardiogenic shock.

Correct Answer is A
Explanation
A. Determining the type of chemical exposure is critical as it guides subsequent treatment and interventions. Different chemicals require different management strategies, including whether to induce vomiting or administer activated charcoal.
B. Calling poison control is important but should occur after identifying the specific chemical involved, as the poison control guidelines often depend on the substance the child was exposed to.
C. Assessing for altered sensorium is important, but the immediate priority is to identify the type of chemical exposure to implement appropriate interventions.
D. Obtaining equipment for gastric lavage may be necessary in certain cases, but this is based on the type of chemical ingested and the child's condition. Identifying the chemical exposure must occur first to determine if gastric lavage is appropriate.
Correct Answer is ["100"]
Explanation
- Total volume of the infusion: 50 mL (saline bag)
- Infusion time: 30 minutes = 0.5 hours (convert minutes to hours)
- We don't need the concentration of gentamicin for this calculation because we're only interested in the total volume delivered per hour.
- Flow rate: Since all the medication is delivered within the infusion time, the flow rate is equal to the total volume divided by the infusion time.
Flow rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Flow rate = 50 mL / 0.5 hours Flow rate = 100.0 mL/hour
Therefore, the nurse should set the pump to deliver 100.0 mL/hour to infuse the 60 mg of gentamicin over 30 minutes.
