A patient has been given a new prescription for warfarin. Which statement indicates the need for additional teaching?
- I will use a soft toothbrush
... [Show More] while taking this medication
- I can eat moderate amounts of foods with vitamin K on a regular basis
- I should report unusual bleeding to my doctor
- I can keep taking a daily aspirin to protect against heart disease (Correct Response)
- I can keep taking a daily aspirin to protect against heart disease
Aspirin increases the effect of warfarin and may cause a higher risk of bleeding; the patient should not take aspirin while on warfarin therapy. All other statements are consistent with safe use of warfarin.
What is the nurse's priority assessment for a patient receiving heparin treatment?
- Assess for elevated liver enzymes
- Assess for inflammation at the injection site
- Assess for bruising or unusual bleeding
- Assess aPTT levels
- Assess for bruising or unusual bleeding
While all options are relevant assessments, bruising or unusual bleeding can be a life threatening adverse effect of heparin treatment, and therefore needs to be the nurse's priority.

A patient who has been receiving oxycodone therapy for chronic pain reports no relief after a 10mg dose. The patient is exhibiting:
- Opioid addiction
- Opioid tolerance
- Drug-seeking behaviour
- Paradoxical CNS stimulation
- Opioid tolerance
Prolonged use of opioid therapy can lead to tolerance, where a patient requires a higher dose of the drug to achieve an analgesic effect.
Which meal choice exhibits a lack of understanding of atorvastatin's drug-food interactions?
- Orange juice, banana, and toast
- Grapefruit juice and yogurt
- Orange juice, bacon, and eggs
- Coffee and croissant
- Grapefruit juice and yogurt
Grapefruit juice is contraindicated for patients on statin therapy and it may increase drug levels in the blood and increase the likelihood of rhabdomyolysis. None of the other choices interact harmfully with atorvastatin.
Which statement indicates that the patient understood the nurse's discharge information about his albuterol inhaler?
- I should use this inhaler five minutes after my beclomethasone inhaler
- I should use this inhaler regularly to manage my asthma
- I should use this inhaler when I am having an acute attack
- I should use this inhaler to reduce inflammation in my airways
- I should use this inhaler when I am having an acute attack
Inhaled albuterol is a rescue medication that reduces bronchoconstriction that is present during acute attacks; it has no effect on inflammation.
A patient is taking promethazine for nausea and oxycodone for pain. What is the nurse's priority assessment?
- Assess for breakthrough pain
- Assess sedation level
- Assess for constipation
- Assess for dizziness
- Assess sedation level
The nurse must assess sedation level as the additive sedative effect when promethazine and oxycodone are administered together can lead to life-threatening respiratory depression. The other side effects do not pose immediate risk and are therefore lower-priority assessments.
Which information is essential to include when educating the patient about clindamycin?
- Clindamycin is primarily bacteriostatic
- Clindamycin should be continued even when feeling better
- Clindamycin can be given to patients with penicillin sensitivities
- Clindamycin can cause a harmless bitter taste
- Clindamycin should be continued even when feeling better
To resolve the infection and prevent the development of resistant pathogens, it is important that the patient understands she must take an entire course of antibiotics even if she is feeling better.
A patient with a penicillin allergy needs antibiotic treatment. Which antibiotic choice would require close monitoring for hypersensitivity due to cross sensitivity?
- vancomycin
- azithromycin
- cefazolin
- levofloxacin
- cefazolin
Cefazolin is a cephalosporin, which is a family of antibiotics that has a high risk of cross-sensitivity in patients with penicillin allergies.
A patient has been receiving 40mg of pravastatin daily. The nurse should closely monitor for which of the following:
- Muscle pain
- Dizziness
- Blurred vision
- Hypoglycemia
- Muscle pain
Muscle pain can be an indicator of rhabdomyolysis, which is a potentially life-threatening adverse effect of pravastatin.
A patient's primary care doctor has prescribed a potassium supplement. This is most likely to counter the effects of which drug?
- furosemide
- metoprolol
- apixaban
- oxybutynin
- furosemide
Furosemide is a diuretic that can cause potassium loss, so a potassium supplement can help to avoid hypokalemia. The other drugs do not have a significant effect on potassium levels.
A patient with angina has been given isosorbide mononitrate. Which of the following symptoms could indicate that the patient is experiencing an adverse reaction to the drug?
- hypertension
- tachycardia
- dry mouth
- fatigue
- tachycardia
Tachycardia is an adverse reaction associated with isosorbide mononitrate.
A diabetic patient who has been using insulin to manage her blood glucose levels was admitted to the hospital. Which of her health problems would prompt the nurse to re-evaluate the patient's daily insulin requirements?
- hypertension
- atrial fibrillation
- infection
- hypothyroidism
- infection
Infection can increase the body's insulin needs, whereas the other health conditions do not have a significant impact on insulin need.
Which of the following statements by a patient receiving levothyroxine for hypothyroidism suggests the need for additional teaching?
- I put an alarm on my phone to remind me to take this at the same time every day.
- I crush the tablet in water because I have trouble swallowing the tablet whole.
- I take this in the morning because it was keeping me awake when I took it at night.
- I take this medication before breakfast with my daily multivitamin.
- I take this medication before breakfast with my daily multivitamin.
Multivitamins could contain elements that prevent levothyroxine's absorption, including calcium, iron, magnesium, or zinc. Taking the medication at the same time everyday is advised, and morning administration may lessen the risk of insomnia. Crushing levothyroxine tablets does not hinder their efficacy.
