The nurse is caring for a client receiving a heparin infusion for disseminated intravascular coagulation (DIC). Which of the following lab results would indicate a sub-therapeutic level? An activated partial thromboplastin time (aPTT) of :……. (normal value: 25-35 seconds)

119 seconds

98 seconds

37 seconds

69 seconds

Answer and Explanation

The Correct Answer is D

A.   A value of 119 seconds would indicate a therapeutic or even elevated level of heparin, as it is much higher than the normal aPTT range.
B.   A value of 98 seconds is still above the normal aPTT range, suggesting that the heparin level is therapeutic, or even too high, but not sub-therapeutic.
C.   This is just slightly above the normal range and might be considered a therapeutic range for someone
on heparin, but it’s not sub-therapeutic.
D.   This aPTT value is above the normal range but likely not high enough to indicate therapeutic heparin levels, which should typically be between 1.5 to 2.5 times the normal aPTT. A sub-therapeutic level could be indicated with a lower value.

Correct Answer is ["13.8"]

Explanation

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

The prescribed dose is 1 mg/kg, so the patient requires 55 mg of furosemide. The medication is supplied at a concentration of 40 mg per 10 mL.

To find out how many mL of furosemide to administer, set up a proportion: 40 mg is to 10 mL as 55 mg is to X mL.

Therefore, the nurse should administer 13.8 mL of furosemide, rounding to the nearest tenth.

A. Administer timolol eye drops to both eyes B. Insert an indwelling catheter C. Administer an antidiarrheal medication D. Provide frequent oral care

Correct Answer is D

Explanation

A. Timolol eye drops are not indicated following the administration of atropine, as atropine has no effect on intraocular pressure.
B. Inserting an indwelling catheter is not necessary for the administration of atropine, which is used to treat bradycardia, not urinary retention.
C. Administering an antidiarrheal medication is unrelated to atropine administration; atropine typically causes dry mouth rather than diarrhea.
D. Atropine is an anticholinergic medication that decreases saliva production, which can lead to dry mouth and discomfort. Frequent oral care is important to prevent oral mucosal irritation and discomfort for the client.
