The nurse is caring for a client who is taking atorvastatin (Lipitor) to assist in lowering his LDL cholesterol. Which lab value must be routinely done with this medication to prevent complications?
Lung function test
Platelet counts
Liver function test
Hemoglobin levels
The Correct Answer is C
A. Lung function tests are not relevant to atorvastatin therapy; they are more commonly associated with medications affecting the respiratory system.
B. Platelet counts are not routinely monitored for patients on atorvastatin unless there are specific concerns related to bleeding or clotting.
C. Liver function tests are critical for patients on atorvastatin because the medication can cause liver enzyme elevations, indicating potential hepatotoxicity. Routine monitoring ensures early detection of any liver complications.
D. Hemoglobin levels are not specifically related to atorvastatin use and are generally monitored in contexts involving anemia or bleeding.

Correct Answer is ["A","B","E","F"]
Explanation
A. Rebound hypotension can occur with the abrupt withdrawal of beta-blockers like esmolol, so clients should be advised against suddenly stopping the medication.
B. Vomiting is not a typical or common side effect of esmolol.
C. Bradycardia is a known effect of beta-blockers, including esmolol, and should be monitored.
D. Esmolol can mask the symptoms of hypoglycemia in diabetic patients, which is an important consideration for patient education.
E. Tremors are not commonly associated with esmolol; rather, they might be seen in other conditions or medications.
F. Bronchoconstriction can occur with non-selective beta-blockers; however, esmolol is cardioselective, so the risk is lower but still possible, especially in patients with underlying respiratory conditions.
Correct Answer is B
Explanation
A. PT/INR is more relevant for monitoring anticoagulant therapy like warfarin, not heparin.
B. This response is accurate; heparin prevents further clot formation but does not dissolve existing clots, which can take time for the body to reabsorb.
C. Heparin begins to exert its effects quickly, and therapeutic levels are not measured by PT/INR but by aPTT or anti-factor Xa levels.
D. Clots do not dissolve immediately after the first dose of heparin; the medication's role is to prevent clot extension.
