The nurse is planning to administer two medications to a client at 0900. Which property of the drugs, if shared by both drugs, indicates a need to closely monitor the client for drug toxicity?
Low bioavailability.
Short half life.
Highly protein bound.
High therapeutic index.
The Correct Answer is C
The property of the drugs that, if shared by both, indicates a need to closely monitor the client for drug toxicity is:
Highly protein bound.
When a drug is highly protein bound, it means that a significant portion of the drug molecules bind to proteins in the bloodstream. This binding can affect the availability and distribution of the drug in the body. If two drugs are highly protein bound and administered together, they may compete for binding sites on the proteins, leading to increased levels of unbound (free) drug in the bloodstream. This can result in higher drug concentrations and an increased risk of drug toxicity.
Closely monitoring the client for drug toxicity is necessary when drugs are highly protein bound because there is a potential for increased drug levels and associated adverse effects. Monitoring for signs and symptoms of drug toxicity, as well as routine laboratory tests to assess liver and kidney function, may be necessary in these cases.
The other properties listed do not necessarily indicate a need for closer monitoring for drug toxicity:
- Low bioavailability refers to the fraction of an administered dose that reaches the systemic circulation in an active form. While low bioavailability can affect the effectiveness of a drug, it does not directly imply a need for closer monitoring for drug toxicity.
- Short half-life refers to the time it takes for half of the drug concentration in the body to be eliminated. While drugs with short half-lives may require more frequent dosing, this property does not inherently suggest a need for closer monitoring for drug toxicity.
- High therapeutic index indicates a wide margin of safety for a drug, meaning that the effective dose is significantly lower than the toxic dose. A high therapeutic index implies that the drug has a wide safety margin and is less likely to cause drug toxicity.

Correct Answer is A
Explanation
Septic shock is a life-threatening condition characterized by a severe infection that leads to systemic inflammation, organ dysfunction, and low blood pressure. Maintaining strict intake and output monitoring is essential to assess the client's fluid balance and response to interventions. It allows the nurse to closely monitor the client's urine output, which is a crucial indicator of renal perfusion and overall organ function.
Monitoring urine output helps the nurse assess the adequacy of tissue perfusion and the client's response to fluid resuscitation. A decrease in urine output can be an early sign of worsening organ dysfunction and a need for further interventions.
While assessing the warmth of extremities is important for evaluating peripheral perfusion, maintaining strict intake and output monitoring takes priority as it provides more comprehensive information about the client's overall fluid status.
Raising the head of the bed 45 degrees (semi-Fowler's position) can help optimize respiratory function and reduce the risk of aspiration, but it is not the most important intervention in this case.
Monitoring blood glucose levels is important, as hyperglycemia can be associated with sepsis. However, in the context of septic shock, maintaining strict intake and output monitoring takes precedence as it directly assesses the client's fluid balance and response to interventions.
It's crucial to note that the management of septic shock requires a multidisciplinary approach, and other interventions, such as administering appropriate antibiotics, initiating fluid resuscitation, and addressing the underlying source of infection, should also be implemented in a timely manner.
Correct Answer is B
Explanation
A) Incorrect- While it's important for UAPs to report changes in a client's condition, the immediate priority is to assess and address the deteriorating condition of the client. The nurse's first action should be to stop the current care being provided and assess the client.
B) Correct- In this situation, the priority is to ensure the safety and well-being of the client. The client's deteriorated condition needs to be assessed promptly by a licensed nurse to determine the appropriate interventions. Stopping the care being provided by the unlicensed assistive personnel (UAP) allows the nurse to focus on the client's immediate needs.
C) Incorrect- Administering oral medications is not the immediate priority in this situation. The client's deteriorating condition takes precedence over administering medications.
D) Incorrect- While investigating the situation and addressing communication gaps is important, the first priority is to assess and address the client's current condition. The nurse needs to take immediate action to ensure the client's safety and well-being.
