A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a
platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical
and should be reported to the physician immediately?
1. Hemoglobin 11 g/dl
2. Platelet of 150,000
3. INR of 2.5
4. Potassium of 2.7 mEq/L --//ANS//--1. Hemoglobin 11 g/dl
This is below normal, but a normal female hemoglobin is 12-14. There is a more critical lab
result.
2. Platelet of 150,000
This is also below the normal values, but is not the most critical lab result.
3. INR of 2.5
This is a therapeutic range for a patient who is taking an anticoagulant for atrial fibrillation

4. Potassium of 2.7 mEq/L
CORRECT - A potassium imbalance for a patient with a history of dysrhythmia can be life-
threatening and can lead to cardiac distress.
While receiving normal saline infusions to treat a GI bleed, the nurse notes that the patient's
lower legs have become edematous and auscultates crackles in the lungs. What should the nurse
do first?
1. Stop the saline infusion immediately
2. Notify Physician
3. Elevate the patient's legs
4. Continue the infusion, since these are normal findings --//ANS//--1. Stop the saline infusion
immediately
CORRECT - the patient has a fluid volume overload as a result of overly rapid fluid
replacement. The nurse should stop the infusion and notify the physician.
2. Notify Physician
This is not the first action the nurse should take.
3. Elevate the patient's legs
This would help with the edema, but is not a priority

4. Continue the infusion, since these are normal findings
This is not a normal finding
The nurse is working in a support group for clients with HIV. Which point is most important for
the nurse to stress?
1. They must inform household members of their condition
2. They must take their medications exactly as prescribed
3. They must abstain from substance use
4. They must avoid large crowds --//ANS//--1. They must inform household members of their
condition
Incorrect - Each patient has a right to privacy of their medical condition. It is their choice
whether they inform household members.
2. They must take their medications exactly as prescribed
CORRECT - Antiretrovirals must be taken exactly as prescribed to prevent drug-resistant strains.
Even missed doses can reduce the effectiveness of future treatment.
3. They must abstain from substance use
Incorrect - While substance use should be discouraged, using safe practices with needles can
prevent transmission of HIV.
4. They must avoid large crowds
, 4|Page
Incorrect - Avoiding large crowds to prevent infection is a priority in the later stages of HIV,
when the patient has AIDS.
A nurse finds a 30-year-old woman experiencing anaphylaxis from a bee sting. Emergency
personnel have been called. The nurse notes the woman is breathing but short of breath. Which
of the following interventions should the nurse do first?
1. Initiate cardiopulmonary resuscitation
2. Check for a pulse
3. Ask the woman if she carries an emergency medical kit
4. Stay with the woman until help comes --//ANS//--1. Initiate cardiopulmonary resuscitation
Incorrect - CPR is premature at this point, and there is another action that can be taken first.
2. Check for a pulse
This is the first step when assessing for initiation of CPR, but CPR is not the best and first course
of action for this situation. The woman is still breathing, which means CPR is not necessary at
this time.
3. Ask the woman if she carries an emergency medical kit
CORRECT - Many patients who have a known history of anaphylaxis carry epi-pens in their
pockets or belongings. This is the best way to stop a hypersensitivity reaction before it becomes
life-threatening.
