Question 1 of 5
Which of the following is an action of the drug Metformin?
Correct Answer: A
Rationale: Metformin is a commonly prescribed medication for the management of type 2 diabetes. One of the primary mechanisms of action of Metformin is to decrease hepatic glucose production. It works by inhibiting gluconeogenesis, which is the process by which the liver produces glucose. By reducing glucose production in the liver, Metformin helps to lower blood sugar levels and improve insulin sensitivity. This action helps to control hyperglycemia in patients with diabetes. The other options provided do not describe the mechanism of action of Metformin, making them incorrect choices.
Question 2 of 5
What is the pharmacologic classification of Amlodipine
Correct Answer: D
Rationale: Amlodipine belongs to the pharmacologic class of calcium channel blockers. It works by inhibiting the influx of calcium ions into smooth muscle cells, leading to vasodilation and lower blood pressure. This medication is commonly used to treat hypertension (high blood pressure) and certain types of angina (chest pain). It is not a beta blocker, 5-HT3 antagonist, or nonopioid analgesic.
Question 3 of 5
The ability of epinephrine to cause hyperglycemia is due to;
Correct Answer: C
Rationale: The ability of epinephrine to cause hyperglycemia is primarily due to its effect on alpha adrenoreceptors in the pancreatic islets of Langerhans. Epinephrine, acting through these alpha adrenoreceptors, inhibits the release of insulin from beta cells in response to elevated blood glucose levels. This results in decreased uptake of glucose by cells, leading to increased blood glucose levels, ultimately causing hyperglycemia. Other effects of epinephrine, such as vasoconstriction and increased heart rate, also contribute to the overall stress response, but the inhibition of insulin release through alpha adrenoreceptors is the main mechanism responsible for its hyperglycemic effects.
Question 4 of 5
What is the reaction of the body to high threshold mechanoreceptor?
Correct Answer: D
Rationale: High threshold mechanoreceptors are responsible for sensing mechanical stimuli such as pressure and touch. When these receptors are activated, one of the body's reactions is to produce analgesia, which refers to the relief of pain or a decreased sensitivity to painful stimuli. This analgesic effect is a protective mechanism that helps reduce the perception of pain in response to potentially harmful mechanical stimuli. Therefore, the reaction of the body to high threshold mechanoreceptors is often associated with analgesia rather than tolerance, withdrawal reflex, inflammation, or suppuration.
Question 5 of 5
Penicillin G has been prescribed for a patient. Which nursing intervention(s) should the nurse perform for this patient? (Select all that apply.)
Correct Answer: A
Rationale: Penicillin G is a beta-lactam antibiotic that can cause severe allergic reactions, including anaphylaxis. Having epinephrine on hand is crucial for managing such emergencies. Collecting a culture and sensitivity before the first dose ensures the infection is caused by a penicillin-susceptible organism. Mouth ulcers are not a common side effect of penicillin, but monitoring for superinfections like oral thrush is important. Limiting fluid intake to 1000 mL/day is incorrect, as adequate hydration helps maintain renal function and prevents crystalluria. No particular interventions are required is incorrect, as penicillin requires careful monitoring for efficacy and adverse effects.
