A client taking atorvastatin develops an increased serum creatine phosphokinase (CK) level. The nurse should assess the client for the onset of which problem?
Peripheral edema.
Muscle tenderness.
Nausea and vomiting.
Excessive bruising.
The Correct Answer is B
Choice A reason: Peripheral edema is not a common side effect of atorvastatin, and it is not related to increased CK levels. CK is an enzyme that is released when muscle tissue is damaged. Peripheral edema is more likely to be caused by heart failure, kidney disease, or venous insufficiency.
Choice B reason: Muscle tenderness is a sign of myopathy, which is a rare but serious adverse effect of atorvastatin. Myopathy is a condition where muscle fibers are damaged and inflamed, leading to muscle weakness and pain. Increased CK levels indicate muscle injury and can be a marker of myopathy. The nurse should monitor the client for muscle symptoms and report them to the prescriber.
Choice C reason: Nausea and vomiting are common gastrointestinal side effects of atorvastatin, but they are not associated with increased CK levels. Nausea and vomiting can be managed by taking the medication with food or reducing the dose.
Choice D reason: Excessive bruising is not a typical side effect of atorvastatin, and it is not linked to increased CK levels. Excessive bruising can be caused by bleeding disorders, anticoagulant therapy, or trauma. The nurse should assess the client for other signs of bleeding, such as hematuria, hematemesis, or melena.

Correct Answer is C
Explanation
Choice A reason: A cool, humidified air is not relevant for this client, as it does not affect the eyes or vision. A cool, humidified air may be beneficial for clients with respiratory conditions, such as asthma or bronchitis.
Choice B reason: A quiet, restful environment is not specific for this client, as it does not address the effects of mydriatic medication on the eyes or vision. A quiet, restful environment may be helpful for clients with stress, anxiety, or insomnia.
Choice C reason: A dimly lit room is the best environment for this client, as it reduces the glare and discomfort caused by mydriatic medication. Mydriatic medication is a type of eye drop that dilates the pupils and prevents them from constricting in response to light. This can improve the examination of the retina and optic nerve, but it also makes the eyes more sensitive to light and reduces the ability to focus on near objects.
Choice D reason: A warm room temperature is not necessary for this client, as it does not affect the eyes or vision. A warm room temperature may be comfortable for clients with cold intolerance, such as hypothyroidism or Raynaud's phenomenon.
Correct Answer is ["0.1"]
Explanation
To find out how many mL of dalteparin are needed for 2500 units, we need to use a proportion formula:
- (units of dalteparin)/(mL of dalteparin) = (units of dalteparin prescribed)/(mL of dalteparin needed)
- We can plug in the values that we know into the formula:
- (5000 units)/(0.2 mL) = (2500 units)/(x mL)
- We can cross-multiply and solve for x:
- 5000x = 2500 x 0.2
- x = (2500 x 0.2)/5000
- x = 0.1
- Therefore, the nurse should administer 0.1 mL of dalteparin to deliver 2500 units of the medication.
