Hemoglobin 12 g/dL
Iron 74 mcg/dL
Lead 18 mcg/dL
Hematocrit 35%
The Correct Answer is C
A. A hemoglobin level of 12 g/dL is within the expected range for an infant.
B. An iron level of 74 mcg/dL is normal for a 9-month-old.
C. This is the correct answer. A lead level of 18 mcg/dL is elevated (≥5 mcg/dL is concerning) and should be reported, as lead toxicity can lead to neurological damage.

Explanation
A. A hemoglobin level of 12 g/dL is within the expected range for an infant.
B. An iron level of 74 mcg/dL is normal for a 9-month-old.
C. This is the correct answer. A lead level of 18 mcg/dL is elevated (≥5 mcg/dL is concerning) and should be reported, as lead toxicity can lead to neurological damage.
D. A hematocrit of 35% is within the expected range for an infant.
Correct Answer is D
Explanation
A. A client who had a right hemisphere stroke – While a stroke may cause weakness on one side, BP measurements can still be taken unless there are additional contraindications like lymphedema or a fistula.
B. A client who had dialysis and is using an arteriovenous shunt in the left lower forearm – BP should never be taken on the arm with an AV shunt, but this does not mean the right arm is unavailable.
C. A client who had blood drawn from the right antecubital area 1 hr ago – Blood draws do not typically affect BP measurements significantly unless there is excessive bruising or infiltration.
D. A client who has a right peripherally inserted central catheter (PICC) – Correct. Blood pressure cuffs can cause compression on the PICC line, leading to catheter occlusion, displacement, or thrombosis. The nurse should instruct the AP to use the opposite arm.
