ATI Pharmacology Proctored Exam 2023 Quizlet
1. A patient with hypertension is taking an ACE inhibitor to lower blood pressure. What should the nurse advise the patient to avoid in their diet?
- A. Vinegar
- B. Apples
- C. Salt substitutes
- D. Tomatoes
Correct answer: C
Rationale: Patients taking ACE inhibitors should avoid salt substitutes as they often contain potassium, which can lead to hyperkalemia. Hyperkalemia is an elevated level of potassium in the blood that can be dangerous, especially for patients on ACE inhibitors. Vinegar, apples, and tomatoes do not pose a risk for patients taking ACE inhibitors. Therefore, the nurse should advise the patient to avoid salt substitutes to prevent potential complications.
2. What is the action of Metformin?
- A. Decreasing intestinal glucose absorption
- B. Increasing sensitivity to insulin
- C. Decreasing hepatic glucose production
- D. All of the above
Correct answer: D
Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.
3. A client has a prescription for Bethanechol to treat urinary retention. Which of the following findings is a manifestation of muscarinic stimulation?
- A. Dry mouth
- B. Hypertension
- C. Excessive perspiration
- D. Fecal impaction
Correct answer: C
Rationale: The correct answer is C: Excessive perspiration. Bethanechol is a muscarinic agonist that stimulates muscarinic receptors. Activation of muscarinic receptors can lead to excessive perspiration (diaphoresis) due to increased cholinergic activity, affecting sweat glands. Dry mouth, hypertension, and fecal impaction are not typically associated with muscarinic stimulation. Dry mouth is more commonly associated with anticholinergic medications, hypertension can be a result of alpha-adrenergic stimulation, and fecal impaction is not a direct effect of muscarinic receptor activation.
4. A healthcare professional is educating clients in an outpatient facility about the use of Insulin to treat type 1 Diabetes Mellitus. For which of the following types of insulin should the professional inform the clients to expect a peak effect 1 to 5 hr after administration?
- A. Insulin glargine
- B. NPH insulin
- C. Regular insulin
- D. Insulin lispro
Correct answer: C
Rationale: Regular insulin typically exhibits a peak effect approximately 1 to 5 hours after administration. It is important for clients to be aware of this timing to ensure optimal management of their blood glucose levels. Insulin glargine, NPH insulin, and Insulin lispro have different onset and peak times compared to Regular insulin. Insulin glargine has a slow, steady release with no pronounced peak, NPH insulin peaks around 4 to 12 hours after administration, and Insulin lispro has a rapid onset and a peak effect around 0.5 to 2.5 hours after administration. Therefore, Regular insulin is the correct choice for a peak effect within the specified time frame.
5. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?
- A. Gram stain
- B. Culture
- C. Sensitivity
- D. Specific gravity
Correct answer: C
Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.
