The nurse is caring for a patient whose blood type is A-. The nurse knows that this patient can receive the following blood types:(SELECT ALL THAT APPLY)

A-

АB

O-

A-

O+

Answer and Explanation

Correct Answer : A,C,D

A.   A patient with blood type A- can receive A- blood, as it matches both the ABO blood group and Rh factor.
B.   A patient with A- blood cannot receive AB blood because the blood type is incompatible in terms of both ABO group and Rh factor. AB blood contains both A and B antigens, which could lead to an immune response in a type A patient.
C.   O- blood is a universal donor for all blood types, meaning it does not contain A or B antigens and does not have the Rh factor, so it can be given to an A- patient.
D.   As already noted, A- blood is compatible with an A- patient because both the ABO group and Rh factor are the same.
E.   O+ blood contains the Rh antigen, and since the patient is A-, they cannot receive Rh-positive blood, as this could cause an immune reaction.

Correct Answer is B

Explanation

A. A low hemoglobin level indicates anemia, not heart failure. While anemia can exacerbate heart failure, it is not the primary indicator.
B. BNP is a biomarker that is elevated in response to heart failure. A level above 100 pg/mL is suggestive of heart failure, and 410 pg/mL indicates significant heart stress and likely acute heart failure.
C. A low sodium level (hyponatremia) can occur in heart failure, but it is not specific enough to confirm the diagnosis. BNP is a more direct indicator of heart failure.
D. This is a normal fibrinogen level and does not indicate heart failure. Fibrinogen is more associated with clotting disorders.

Correct Answer is ["11"]

Explanation

The patient weighs 121 lbs, which is approximately 55 kilograms (121 ÷ 2.2).

Next, multiply the patient's weight in kilograms by the dosage prescribed, which is 20 units/kg. This results in a total dosage of 1100 units (55 kg × 20 units/kg).

The medication is supplied as 25,000 units in 250 mL, so to find out how many mL of medication is needed, set up a proportion: 25,000 units is to 250 mL as 1100 units is to X mL. Solving for X gives you 11 mL (1100 units × 250 mL ÷ 25,000 units).

Therefore, the nurse will administer 11 mL of Heparin to the patient.
