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.

Answer and Explanation

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 D

Explanation

The correct answer is choice D: Begin chest compressions at 100/minute.

Choice A rationale:

Observing for swelling at the fracture site is not immediately relevant in this emergency situation. The priority is to address the lack of pulse and respiration.

Choice B rationale:

Analyzing the cardiac rhythm in another lead is unnecessary when the patient has no pulse and is not breathing. Immediate life-saving measures are required.

Choice C rationale:

Obtaining a 12-lead electrocardiogram is not the priority in this scenario. The patient needs immediate resuscitation efforts.

Choice D rationale:

Beginning chest compressions at 100/minute is the correct intervention. The absence of a carotid pulse and spontaneous respirations indicates cardiac arrest, and chest compressions are essential to maintain circulation and oxygenation until further help arrives.

A. Protect the site from getting wet during bathing. B. Gently pat the skin dry after rinsing with water. C. Frequently apply moisturizers to prevent dry skin. D. Use a sponge to debride the affected area.

Correct Answer is B

Explanation

A.Protect the site from getting wet during bathing. While it is important to avoid prolonged soaking, gentle rinsing with water is usually allowed. Complete avoidance of water is not typically necessary.Gentle bathing is important for hygiene.

B.Gently patting the skin dry after rinsing with water is a good practice as it helps to minimize friction and irritation to the sensitive skin. Rubbing or scrubbing the skin should be avoided.

C. Applying moisturizers to prevent dry skin can be beneficial for overall skin health, but it is important to consult with the healthcare team and follow specific instructions regarding the use of moisturizers during radiation therapy. Certain types of moisturizers or creams may interfere with the radiation treatment or cause skin irritation. Frequent application is not always necessary. Over-hydration can soften the skin and increase vulnerability.

D.Using a sponge to debride the affected area is not recommended during radiation therapy. The skin in the radiation treatment field is already sensitive and prone to damage, and using a sponge for debridement can further traumatize the skin. It is important to avoid any abrasive or rough handling of the treated skin.
