Levothyroxine is prescribed for a client diagnosed with hypothyroidism. Upon
review of the client's record, the nurse notes that the client is taking warfarin.
Which modification to the plan of care would the nurse review with the client's
primary health care provider?
1. A decreased dosage of levothyroxine
2. An increased dosage of levothyroxine
3. A decreased dosage of warfarin sodium
4. An increased dosage of warfarin sodium - Correct Answer -A decreased dosage
of warfarin sodium
Levothyroxine accelerates the degradation of vitamin K-dependent clotting
factors. As a result, the effects of warfarin are enhanced. If thyroid hormone
replacement therapy is instituted in a client who has been taking warfarin, the
dosage of warfarin would be reduced
A client received 20 units of Humulin N insulin subcutaneously at 08:00. At what
time would the nurse plan to assess the client for a hypoglycemic reaction?
,1. 10:00
2. 11:00
3. 17:00
4. 24:00 - Correct Answer -17:00
Humulin N is an intermediate-acting insulin. The onset of action is 60 to 120
minutes, it peaks in 6 to 14 hours, and the duration of action is 16 to 24 hours.
Hypoglycemic reactions most likely occur during peak time.
The nurse teaches a client newly diagnosed with type 1 diabetes about storing
Humulin N insulin. Which statement indicates to the nurse that the client
understood the discharge teaching?
1. "I would keep the insulin in the cabinet during the day only."
2. "I know I have to keep my insulin in the refrigerator at all times."
3. "I can store the open insulin bottle in the kitchen cabinet for 1 month."
4. "The best place for my insulin is on the windowsill, but in the cupboard is just as
good." - Correct Answer -"I can store the open insulin bottle in the kitchen cabinet
for 1 month."
An insulin vial in current use can be kept at room temperature for 1 month
without significant loss of activity. Direct sunlight and heat must be avoided.
Therefore, options 1, 2, and 4 are incorrect.
, The new registered nurse (RN) is orienting on the cardiac unit. Which statement
by the new RN indicates an understanding of an early indication of fluid volume
deficit due to blood loss?
1. "Pulse rate will increase."
2. "Blood pressure will decrease."
3. "Edema will be present in the legs."
4. "Crackles in the lungs will be present." - Correct Answer -"Pulse rate will
increase."
The cardiac output is determined by the volume of the circulating blood, the
pumping action of the heart, and the tone of the vascular bed. Early decreases in
fluid volume are compensated for by an increase in the pulse rate. Although the
blood pressure will decrease, it is not the earliest indicator. Edema and crackles in
the lungs indicate an increase in fluid volume.
A nursing student who is researching a medication at the nurses' station asks the
registered nurse (RN) what the function of an alpha-adrenergic receptor is, and
where the receptors are primarily found. The RN educates the nursing student.
Which statement by the nursing student indicates that teaching has been
effective?
1. "The peripheral arteries and veins; when stimulated they cause
vasoconstriction."
2. "Arterial and bronchial walls; when stimulated they cause vasodilation and
bronchodilation."
