ATI Pharmacology Exam 2 Questions
Question 1 of 5
A nurse is preparing to administer hydrocortisone sodium succinate 250 mg via IV bolus every 6 hr. Available is hydrocortisone sodium succinate 1000 mg/8 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale:
To calculate the mL to administer, use the formula: Desired dose (250 mg) x Volume available (8 mL) / Stock dose (1000 mg) = X mL. Substituting the values, we get 250 x 8 / 1000 = 2.
Therefore, the nurse should administer 2 mL. Option B is correct. Option A (1 mL) is too low as it would be less than the required dose. Option C (3 mL) and Option D (4 mL) are too high as they exceed the required dose.
Question 2 of 5
A nurse is assessing a client after administering IV vancomycin. Which of the following findings is the nurse's priority to report to the provider?
Correct Answer: B
Rationale: The correct answer is B: Audible inspiratory stridor. This finding is indicative of a potentially serious adverse reaction known as anaphylaxis, which requires immediate medical intervention. Stridor suggests upper airway obstruction that can lead to respiratory distress and compromise the client's airway. Reporting this symptom promptly is crucial to prevent further complications.
Choices A, C, and D are less urgent and can be addressed after ensuring the client's airway is stable. A headache, tinnitus, and localized redness are common side effects of vancomycin and can be managed with appropriate interventions.
Question 3 of 5
A nurse is teaching a client who takes warfarin daily. Which of the following statements by the client indicates a need for further teaching?
Correct Answer: C
Rationale: Statement C indicates a need for further teaching because ginger root can interact with warfarin, potentially increasing the risk of bleeding due to its blood-thinning properties. The client should be advised to avoid ginger root while taking warfarin to prevent adverse effects. Statements A, B, and D are all appropriate behaviors for someone taking warfarin. Eating a green salad is fine as long as the client maintains a consistent intake of vitamin K, taking the medication at the same time daily helps with consistency, and regular INR checks are necessary for monitoring the medication's effectiveness.
Question 4 of 5
When hormones, formed within a cell, move across the cell membrane, the process is call what?
Correct Answer: D
Rationale: The correct answer is D: Exocytosis. Exocytosis is the process by which hormones or other substances formed within a cell are transported outside the cell through vesicles fusing with the cell membrane. This allows the release of these substances into the extracellular environment. Phagocytosis (
A), Endocytosis (
B), and Pinocytosis (
C) are all processes involving the uptake of substances into the cell, not the release of substances out of the cell.
Therefore, they are not the correct answers in this context.
Question 5 of 5
A nurse in a coronary care unit is admitting a client who has had CPR following a cardiac arrest. The client is receiving lidocaine IV at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
Correct Answer: A
Rationale: The correct answer is A: Prevents dysrhythmias. Lidocaine is commonly used in the management of dysrhythmias, particularly ventricular arrhythmias. It works by stabilizing the cardiac cell membrane, preventing abnormal electrical activity that can lead to life-threatening rhythms.
Choice B (Relieves pain) is incorrect as lidocaine is not used for pain relief in this context.
Choice C (Dissolves blood clots) is incorrect as lidocaine does not have anticoagulant properties.
Choice D (Slows intestinal motility) is incorrect as lidocaine does not affect intestinal motility.
