1. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?
- A. The client has a decrease in troponin levels.
- B. The client has a regular heart rhythm.
- C. The client experiences a decrease in episodes of angina.
- D. The client's blood pressure remains stable.
Correct answer: C
Rationale: The correct answer is C. A decrease in episodes of angina is an indicator of Aspirin's effectiveness in preventing cardiovascular events. Aspirin works by inhibiting platelet aggregation, thereby reducing the formation of blood clots that could lead to angina episodes or more severe cardiovascular complications. Choices A, B, and D are incorrect because troponin levels, heart rhythm, and blood pressure are not direct indicators of Aspirin's effectiveness in preventing cardiovascular events.
2. Which of the following is the antidote for Heparin toxicity?
- A. Protamine
- B. Methylene blue
- C. N-acetylcysteine
- D. Glucagon
Correct answer: A
Rationale: Protamine is the specific antidote for Heparin toxicity. Heparin is an anticoagulant medication, and if an overdose occurs or if there is excessive bleeding due to Heparin use, protamine, a positively charged molecule, can neutralize the anticoagulant effects of Heparin by forming a complex with it. This binding prevents Heparin from further inhibiting coagulation factors and helps in reversing its effects.
3. During an admission assessment for a client with severe Aspirin toxicity, which finding should the nurse expect?
- A. Body temperature 35°C (95°F)
- B. Lung crackles
- C. Cool, dry skin
- D. Respiratory depression
Correct answer: D
Rationale: In severe Aspirin toxicity, respiratory depression is an anticipated finding due to the development of respiratory acidosis. Aspirin toxicity can lead to metabolic acidosis, causing the individual to hyperventilate initially to compensate. However, as the condition progresses, respiratory depression can occur, resulting in impaired gas exchange and respiratory acidosis.
4. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?
- A. 0.8 mL
- B. 0.75 mL
- C. 0.5 mL
- D. 1 mL
Correct answer: A
Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.
5. When discussing immunizations, which vaccine series is typically completed before a child's first birthday?
- A. Pneumococcal conjugate vaccine
- B. Meningococcal conjugate vaccine
- C. Varicella vaccine
- D. Rotavirus vaccine
Correct answer: D
Rationale: The correct answer is D, Rotavirus vaccine. The rotavirus vaccine series is usually completed before a child's first birthday. It is given to infants in a series of doses starting at 2 months of age and must be completed by 8 months of age. This vaccine helps protect against severe diarrhea and vomiting caused by rotavirus infection, which is common in infants and young children. Choices A, B, and C are incorrect because the Pneumococcal conjugate vaccine, Meningococcal conjugate vaccine, and Varicella vaccine are not typically completed before a child's first birthday.
