Question 1 of 5
The client is receiving a continuous heparin infusion. Which laboratory value should the nurse monitor most closely?
Correct Answer: C
Rationale: Heparin’s anticoagulant effect is monitored by aPTT, with a therapeutic range of 1.5–2.5 times the control value. Platelet count is monitored for heparin-induced thrombocytopenia, but PT and INR are for warfarin.
Question 2 of 5
A female client presents to the obstetric-gynecology clinic for a pregnancy test, the result which turns out to be positive. Her last menstrual period began December 10, 1993. Using Nägele's rule, the nurse estimates her date of delivery to be:
Correct Answer: A
Rationale: According to Nägele's rule, the estimated date of delivery is calculated by adding 7 days to the date of the first day of the normal menstrual period (December 10 + 7 days = December 17), and then by counting back 3 months (December 17 - 3 mo = September 17). (B, C,
D) These answers are incorrect.
Question 3 of 5
The most important reason to closely assess circumferential burns at least every hour is that they may result in:
Correct Answer: D
Rationale: Full-thickness circumferential burns are nonelastic and create an internal tourniquet effect, compromising distal blood flow in extremities or respiratory motion in the torso, leading to loss of peripheral pulses.
Question 4 of 5
A client is admitted with symptoms of vertigo and syncope.
Correct Answer: C
Rationale: Left subclavian artery obstruction can cause subclavian steal syndrome, leading to vertigo, syncope, and radial pulse differences (>10 bpm) due to blood flow reversal. Memory loss (
A), numbness (
B), and headache (
D) are unrelated.
Question 5 of 5
The nurse is teaching a 10-year-old insulin-dependent diabetic how to administer insulin. Which one of the following steps must be taught for insulin administration?
Correct Answer: B
Rationale: Sites for injection need to be rotated, including abdominal sites, to enhance insulin absorption. The pinch technique is the most effective method for obtaining skin tightness to allow easy entrance of the needle to subcutaneous tissues. Massaging the site of injection facilitates absorption of the insulin. Changing the needle will break the sterility of the system. It has become acceptable practice to reuse disposable needles and syringes for 3-7 days.
