The parents of a 6-year-old recently diagnosed with asthma should be taught that symptoms of an acute episode of asthma are due to which physiological response?
- A. Inflammation of the mucous membrane and bronchospasm
- B. Increased mucus production and airway obstruction
- C. Hyperinflation of the lungs and alveolar collapse
- D. Bronchoconstriction and airway inflammation
Correct Answer: D
Rationale: The correct answer is D: Bronchoconstriction and airway inflammation. During an acute asthma episode, bronchoconstriction and airway inflammation occur, leading to difficulty breathing. Choices A, B, and C are incorrect. Inflammation of the mucous membrane and bronchospasm (Choice A) are part of the pathophysiology of asthma but do not fully explain the symptoms during an acute episode. Increased mucus production and airway obstruction (Choice B) are also seen in asthma but are not the primary cause of acute symptoms. Hyperinflation of the lungs and alveolar collapse (Choice C) are not typical features of an acute asthma episode.

In a client with liver cirrhosis admitted with ascites and jaundice, which laboratory value is most concerning to the nurse?
- A. Serum albumin of 3.0 g/dl
- B. Bilirubin of 3.0 mg/dl
- C. Ammonia level of 80 mcg/dl
- D. Prothrombin time of 18 seconds
Correct Answer: C
Rationale: An elevated ammonia level of 80 mcg/dl is most concerning in a client with liver cirrhosis because it may indicate hepatic encephalopathy, a serious complication. Serum albumin, though low, is expected in cirrhosis and contributes to ascites. Bilirubin elevation is common in liver disease but may not be the most concerning in this case. Prothrombin time is typically prolonged in liver disease but may not be as acute as an elevated ammonia level suggesting hepatic encephalopathy.
The unit clerk reports to the charge nurse that a healthcare provider has written several prescriptions that are illegible and it appears the healthcare provider used several unapproved abbreviations in the prescriptions. What actions should the charge nurse take?
- A. Call the healthcare provider who wrote the prescription
- B. Attempt to clarify the prescriptions with the pharmacist
- C. Administer the medications as prescribed
- D. Ask another healthcare provider for clarification
Correct Answer: A
Rationale: The correct action for the charge nurse to take is to call the healthcare provider who wrote the illegible prescriptions. It is crucial to clarify illegible prescriptions directly with the provider to ensure patient safety and prevent medication errors. Option B, attempting to clarify with the pharmacist, may lead to misinterpretation and is not the recommended first step. Administering the medications as prescribed without clarity can jeopardize patient safety, making option C incorrect. Asking another healthcare provider for clarification (option D) may not be effective as the responsibility lies with the provider who wrote the prescription.
The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?
- A. Low bioavailability
- B. Rapid onset of action
- C. Short half-life
- D. Narrow therapeutic index
Correct Answer: D
Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
The nurse and an unlicensed assistive personnel (UAP) are providing care for a client with a nasogastric tube (NGT) when the client begins to vomit. How should the nurse manage this situation?
- A. Direct the UAP to measure the emesis while the nurse irrigates the NGT
- B. Stop the NGT feed and notify the healthcare provider
- C. Increase the NGT suction pressure
- D. Elevate the head of the bed
Correct Answer: A
Rationale: During vomiting in a client with an NGT, it is essential for the nurse to direct the UAP to measure the emesis to monitor the output. This helps in assessing the client's condition and response to treatment. Meanwhile, irrigating the NGT can be beneficial to relieve any obstruction that might be contributing to the vomiting. Stopping the NGT feed and notifying the healthcare provider (choice B) is important but not the immediate action needed. Increasing the NGT suction pressure (choice C) is unnecessary and can lead to complications. Elevating the head of the bed (choice D) is a general intervention to prevent aspiration but may not address the immediate issue of managing the vomiting episode and potential tube obstruction.
A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding requires immediate intervention?
- A. Serum glucose of 300 mg/dL
- B. Serum potassium of 5.5 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Positive urine ketones
Correct Answer: C
Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.
