Nclex Questions Management of Care - Nurselytic

Correct Answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability.
Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.

Correct Answer: C

Rationale: When a pleural drainage system is cracked, the nurse's initial action should be to change the drainage system. This is essential to prevent potential complications like air leaks or infections. While observing the client's response and checking for leaks are important steps, they are secondary to addressing the immediate issue of the cracked system. Notifying the physician, though necessary, can be carried out once the primary concern of the damaged system is resolved.

Correct Answer: C

Rationale: In an obstetrical emergency, the immediate priority after the baby delivers is to clear the baby's airway by suctioning the mouth and nose to ensure effective breathing. This action helps prevent potential complications like meconium aspiration. Cutting the umbilical cord, wrapping the baby in a blanket, or placing extra padding under the mother can follow once the baby's airway is clear.
Therefore, suctioning the baby's mouth and nose is the most critical and time-sensitive intervention in this scenario. Placing extra padding under the mother is not the immediate priority as ensuring the baby's airway is clear. Cutting the umbilical cord and wrapping the baby in a clean blanket are important but can wait until after ensuring the baby's breathing is not compromised.

Correct Answer: D

Rationale: Gentle bubbling is a normal finding for a client with a pleural drainage system to suction, so it simply needs to be documented for monitoring purposes. If the bubbling becomes vigorous, it could indicate a leak, which would then require further investigation by the nurse.
Therefore, the correct action at this point is to document the finding. Notifying the physician is not necessary for gentle bubbling as it is expected. Clamping the chest tube or replacing the system is inappropriate and could potentially harm the client as there is no indication for such actions based on the scenario provided.

Correct Answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (
Choice
A) is related to the dose of a drug needed to produce a specific effect. Efficacy (
Choice
B) refers to a drug's ability to generate the desired effect. Kinetics (
Choice
C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.
