1. A client with amyotrophic lateral sclerosis has a percutaneous endoscopic gastrostomy (PEG) tube for the administration of feedings and medications. Which nursing action is appropriate?
- A. Pulverize all medications into a powdery condition
- B. Squeeze the tube before using it to break up stagnant liquids
- C. Cleanse the skin around the tube daily with hydrogen peroxide
- D. Flush adequately with water before and after using the tube
Correct answer: D
Rationale: For a client with a percutaneous endoscopic gastrostomy (PEG) tube, flushing the tube adequately with water before and after use is essential. This action helps prevent clogging and ensures the proper administration of feedings and medications. Choice A is incorrect because pulverizing all medications into a powdery condition is not necessary for PEG tube administration. Choice B is incorrect as squeezing the tube to break up stagnant liquids may damage the tube. Choice C is incorrect because cleansing the skin around the tube daily with hydrogen peroxide can be too harsh and lead to skin irritation.
2. The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. The infant was born two weeks after his due date and is described as a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?
- A. Has your son had any immunizations yet?
- B. Is your son sleepy and difficult to feed?
- C. Are you breastfeeding or bottle-feeding your son?
- D. Were any relatives born with birth defects?
Correct answer: B
Rationale: The correct answer is B. Excessive sleepiness and difficulty feeding can be signs of hypothyroidism in infants. Asking about the infant's sleepiness and feeding pattern is crucial in assessing for hypothyroidism. Choice A is incorrect because immunizations are not directly related to hypothyroidism. Choice C is about feeding method and not specific to hypothyroidism. Choice D is unrelated as it asks about relatives with birth defects, which does not directly assess the infant's condition.
3. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: C
Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.
4. A client with a history of chronic kidney disease presents with increased swelling and shortness of breath. What is the nurse's priority action?
- A. Administer oxygen at 2 liters per nasal cannula.
- B. Administer a diuretic as prescribed.
- C. Monitor the client's vital signs.
- D. Reposition the client to improve lung expansion.
Correct answer: B
Rationale: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.
5. A client with a history of rheumatoid arthritis is prescribed methotrexate. Which laboratory value should the nurse monitor closely?
- A. Liver function tests
- B. Complete blood count
- C. Serum creatinine
- D. Prothrombin time
Correct answer: C
Rationale: Serum creatinine should be closely monitored in a client receiving methotrexate, as the medication can cause nephrotoxicity. Monitoring serum creatinine levels helps assess kidney function and detect potential nephrotoxic effects of methotrexate. Liver function tests (Choice A) are important to monitor for hepatotoxicity caused by methotrexate. While methotrexate can cause bone marrow suppression, leading to anemia, leukopenia, and thrombocytopenia, monitoring a complete blood count (Choice B) is essential but not the priority in this case. Prothrombin time (Choice D) is not typically affected by methotrexate therapy and is not the primary laboratory value to monitor in this situation.
