1. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?
- A. 10 ml
- B. 12.5 ml
- C. 15 ml
- D. 17.5 ml
Correct answer: B
Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
2. The client is being taught how to take alendronate (Fosamax) for osteoporosis treatment. Which statement indicates that the client needs further teaching?
- A. I should take this medication at bedtime
- B. I will need to take this medication for at least 3 years
- C. I should sit up for 30 minutes after taking the medication
- D. I should take this medication with a full glass of water
Correct answer: A
Rationale: The correct answer is A because taking Fosamax at bedtime is incorrect. It should be taken in the morning with a full glass of water to prevent esophageal irritation. Choice B is correct; alendronate is typically taken for several years to treat osteoporosis. Choice C is correct as remaining upright for 30 minutes after taking Fosamax helps prevent esophageal irritation. Choice D is also correct as taking alendronate with a full glass of water is necessary to ensure proper absorption.
3. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Partial thromboplastin time (PTT)
- D. Hemoglobin level
Correct answer: C
Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.
4. Which nursing diagnosis has the highest priority when planning care for a client in cardiogenic shock?
- A. Risk for imbalanced body temperature
- B. Excess fluid volume
- C. Fatigue
- D. Ineffective Tissue Perfusion
Correct answer: D
Rationale: In cardiogenic shock, the priority nursing diagnosis is Ineffective Tissue Perfusion. This diagnosis indicates that the client is not receiving adequate oxygenated blood to tissues, putting vital organs at risk. Addressing ineffective tissue perfusion is crucial to prevent organ damage and ensure the client's survival. The other options, such as 'Risk for imbalanced body temperature,' 'Excess fluid volume,' and 'Fatigue,' are important but secondary to the immediate threat of inadequate tissue perfusion in cardiogenic shock.
5. A male client admitted three days ago with respiratory failure is intubated, and 40% oxygen per facemask is initiated. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?
- A. Exhibits adequate tissue perfusion
- B. Remains free of injury
- C. Remains free of infection
- D. Maintains effective breathing pattern
Correct answer: D
Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.
