1. In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set?
- A. 15 drops per milliliter
- B. 60 drops per milliliter
- C. 20 drops per milliliter
- D. 10 drops per milliliter
Correct answer: B
Rationale: A microdrop set delivers 60 drops per milliliter of IV fluid. This allows for a more precise control of the infusion rate. The correct choice is B because it provides the desired microdrop rate. Choices A, C, and D are incorrect. A delivers 15 drops per milliliter, which is a macrodrop set. C delivers 20 drops per milliliter, also a macrodrop set. D delivers 10 drops per milliliter, another macrodrop set. Therefore, the correct choice for a microdrop set is B.
2. What is the priority nursing action for a laboring client dilated to 6 cm receiving an epidural?
- A. Continuous monitoring of maternal blood pressure.
- B. Frequent auscultation of the fetal heart rate.
- C. Administering an IV fluid bolus of at least 500 cc.
- D. Frequent monitoring of the maternal temperature.
Correct answer: A
Rationale: The priority nursing action for a laboring client dilated to 6 cm receiving an epidural is continuous monitoring of maternal blood pressure. This is crucial because epidural anesthesia can lead to a precipitous drop in blood pressure, which can be dangerous for both the mother and fetus by reducing cardiac output and placental perfusion. While frequent auscultation of the fetal heart rate is important, it is not the priority in this situation. Administering an IV fluid bolus of at least 500 cc may not be necessary if the client's blood pressure is stable. Monitoring the maternal temperature is also essential but takes precedence over blood pressure monitoring.
3. After applying oxygen using bi-nasal prongs to a client who is having chest pain, the nurse should implement which intervention?
- A. Have the client take slow deep breaths in through their mouth and out through their nose.
- B. Post signs indicating that oxygen is in use on the client's door and in their room
- C. Apply Vaseline petroleum to both nares and 2 by 2 gauze around the oxygen tubing at the client's ears
- D. Encourage the client to hyperextend the neck, take a few deep breaths and cough.
Correct answer: A
Rationale: After applying oxygen using bi-nasal prongs to a client with chest pain, it is essential for the nurse to post signs indicating that oxygen is in use on the client's door and in their room. This safety precaution alerts healthcare providers and visitors that the client is receiving oxygen therapy, reducing the risk of accidents or misunderstandings. Choice A is incorrect because instructing the client to take slow deep breaths is not the appropriate intervention after applying oxygen. Choice C suggests applying Vaseline and gauze, which is unnecessary and not a standard practice. Choice D advising the client to hyperextend the neck, take deep breaths, and cough is not indicated after applying oxygen therapy and could potentially be harmful.
4. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
- A. metastatic liver cancer
- B. gram-negative septicemia
- C. pernicious anemia
- D. iron-deficiency anemia
Correct answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding compared to the other conditions listed. Pernicious anemia is a condition resulting from vitamin B12 deficiency due to the absence of intrinsic factor, necessary for B12 absorption. While pernicious anemia can lead to neurological issues, it is not directly linked to an increased risk of bleeding. Metastatic liver cancer can cause liver dysfunction leading to coagulopathy, gram-negative septicemia can result in disseminated intravascular coagulation (DIC), and iron-deficiency anemia can lead to microcytic hypochromic red blood cells, increasing the risk of bleeding. Therefore, pernicious anemia is the least likely to be associated with an increased potential for bleeding out of the options provided.
5. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63 mmHg, HCO3 23, and oxygenation saturation (SaO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?
- A. tuberculosis (TB)
- B. pneumonia
- C. pleural effusion
- D. hypoxia
Correct answer: D
Rationale: A combined low PO2 and low SaO2 indicate hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low due to hypoxia stimulating hyperventilation, but the given ABG values specifically point to hypoxia as the primary issue.
