possible drug toxicity.

decreased therapeutic effects.

altered drug absorption.

increased drug metabolism.

Answer and Explanation

The Correct Answer is A

A. A reduced plasma albumin level can lead to increased free drug levels in the bloodstream, raising the risk of drug toxicity, particularly for highly protein-bound medications.

B. Decreased therapeutic effects are less likely because the decrease in albumin can lead to higher free drug concentrations, which may actually increase effects rather than decrease them.

C. Altered drug absorption is generally not directly influenced by plasma albumin levels; it relates more to gastrointestinal factors.

D. Increased drug metabolism is not a direct consequence of lower albumin levels; instead, the concern is primarily about increased free drug concentrations and potential toxicity.

Correct Answer is D

Explanation

A. Nitrates do not share a cross-sensitivity with penicillin and are safe to use in this client.

B. Tetracycline is a different class of antibiotics and does not have cross-sensitivity with penicillin.

C. Aminoglycosides also do not have cross-sensitivity with penicillin and can be safely administered.

D. Cephalosporins are structurally related to penicillin and have a risk of cross-sensitivity; thus, they should not be given to a client with a history of anaphylaxis to penicillin.

A. Constricted pupils B. Warm, dry skin C. Increased heart rate D. Decreased urine output

Correct Answer is C

Explanation

A. Constricted pupils are not an expected response to isoproterenol, which generally causes dilation of the pupils due to sympathetic stimulation.

B. Warm, dry skin is not a direct indicator of the effectiveness of isoproterenol; it could result from various factors unrelated to the medication's action.

C. Increased heart rate indicates that isoproterenol, which is a beta-agonist, is effectively stimulating the beta-adrenergic receptors, leading to increased cardiac output and heart rate.

D. Decreased urine output is not a sign of effectiveness and could indicate adverse effects such as reduced renal perfusion.
