The nurse is caring for a patient who is experiencing anaphylaxis. The family asks the nurse why the patient is having difficulty breathing. The nurse responds based on what knowledge?
- A. Bronchoconstriction in response to the allergen.
- B. Compensation for a rapid fall in blood pressure.
- C. Reflex tachycardia.
- D. Seizures are likely to occur.
- G. A
Correct Answer: Bronchoconstriction from allergens causes breathing difficulty in anaphylaxis. Hypotension, tachycardia, and seizures are secondary or unrelated.
Rationale: The correct answer is A: Bronchoconstriction in response to the allergen. During anaphylaxis, the body releases histamine causing bronchoconstriction, leading to difficulty breathing. This is a direct response to the allergen and can lead to respiratory distress. Choice B, compensation for a rapid fall in blood pressure, is incorrect as hypotension is a secondary effect of anaphylaxis. Choice C, reflex tachycardia, is also incorrect as tachycardia is a compensatory response to hypotension, not the cause of difficulty breathing. Choice D, seizures are likely to occur, is incorrect as seizures are not a common manifestation of anaphylaxis. Therefore, the correct answer is A as it directly relates to the pathophysiology of anaphylaxis.

When beginning herbal products, the nurse understands that the best way to identify allergic or other adverse reactions is to have the client:
- A. Take less than the recommended dose initially.
- B. Never take with prescription medications.
- C. Check with a reputable pharmacist.
- D. Use only one herbal preparation at a time.
- G. D
Correct Answer: Lower doses may not reveal reactions. Avoiding prescriptions isn't always necessary. Pharmacist consultation is good but not best for identification. One product at a time isolates reactions.
Rationale: The correct answer is D: Use only one herbal preparation at a time. By using only one herbal preparation at a time, the nurse can accurately identify any allergic or adverse reactions that may occur. This approach allows for clear isolation of the effects of each herb, making it easier to pinpoint the source of any reactions. Taking lower doses (choice A) may not always reveal reactions as some individuals may still have adverse effects. Never taking herbal products with prescription medications (choice B) is overly restrictive and not always necessary. Checking with a reputable pharmacist (choice C) is a good practice for general information but may not be the most effective way to identify specific reactions.
Complete the following statement: “Drugs used for the treatment of depression and a range of anxiety disorders including panic, social phobia, and post-traumatic stress disorder are known as…â€
- A. Barbiturates
- B. Rebound insomnia
- C. Antidepressants
- D. Anxiolytics
- G. C
Correct Answer: Barbiturates are sedatives. Rebound insomnia isn't a drug. Antidepressants treat depression and anxiety disorders. Anxiolytics focus on anxiety.
Rationale: The correct answer is C: Antidepressants. Antidepressants are drugs specifically designed to treat depression and various anxiety disorders, including panic, social phobia, and post-traumatic stress disorder. They work by balancing neurotransmitters in the brain to improve mood and reduce symptoms of anxiety. Barbiturates (A) are sedatives, not typically used for treating anxiety or depression. Rebound insomnia (B) is a phenomenon where insomnia worsens after discontinuing sleep medications, not a class of drugs. Anxiolytics (D) are drugs that specifically target anxiety symptoms, but they do not usually address depression. Therefore, the correct choice is C as it accurately describes the drugs used for treating depression and a range of anxiety disorders.
Class of drugs derived from barbituric acid that act as CNS depressants and are used for their sedative and anti- seizure effect are known as _
- A. Antidepressants
- B. Anxiolytics
- C. Barbiturates
- D. Benzodiazepines
- G. C
Correct Answer: Antidepressants treat mood disorders. Anxiolytics reduce anxiety but aren't barbituric-derived. Barbiturates fit the description. Benzodiazepines aren't barbituric-based.
Rationale: The correct answer is C: Barbiturates. Barbiturates are drugs derived from barbituric acid, acting as CNS depressants for sedative and anti-seizure effects. Antidepressants (A) are used for mood disorders, not CNS depression. Anxiolytics (B) are for anxiety and not all are barbituric-derived. Benzodiazepines (D) are a different class of CNS depressants, not derived from barbituric acid. Therefore, choice C is the most appropriate based on the specific description provided in the question.
What is the priority action for a nurse caring for a client with a urinary tract infection before administering prescribed antibiotics?
- A. Obtain a blood pressure
- B. Obtain a urine specimen for culture and sensitivity
- C. Obtain a PTT
- D. Obtain a platelet count .
- G. B
Correct Answer: Blood pressure is routine, not priority. Urine culture identifies the bacteria and antibiotic sensitivity before treatment. PTT and platelet counts are unrelated to UTI antibiotics.
Rationale: The correct answer is B: Obtain a urine specimen for culture and sensitivity. This is the priority action because it helps identify the specific bacteria causing the UTI and determines the most effective antibiotic for treatment. This step is crucial for appropriate antibiotic therapy and to prevent antibiotic resistance. A: Obtaining a blood pressure is a routine assessment and not directly related to UTI treatment. C and D: Obtaining a PTT and platelet count are not necessary for assessing or treating a UTI; these tests are unrelated to UTI management. Therefore, the priority action for a nurse caring for a client with a UTI is to obtain a urine specimen for culture and sensitivity.
The patient with tuberculosis is now on isoniazid (INH). Which laboratory test should the nurse monitor?
- A. BUN
- B. PT and PTT
- C. Liver enzymes (LFTs)
- D. CBC
- G. C
Correct Answer: BUN, PT/PTT, and CBC aren't specific to INH. Liver enzymes are monitored due to INH's hepatotoxicity risk.
Rationale: The correct answer is C. The nurse should monitor liver enzymes (LFTs) in a patient on isoniazid (INH) due to the risk of hepatotoxicity associated with this medication. 1. Isoniazid is known to cause liver damage in some patients. 2. Monitoring liver enzymes can help detect any liver dysfunction early. 3. LFTs include tests such as ALT, AST, and bilirubin, which can indicate liver damage. 4. Regular monitoring of LFTs is essential to ensure the safe use of INH. Incorrect choices: A. BUN is not specific to INH. B. PT and PTT are not directly related to INH use. D. CBC is not specifically required for monitoring INH therapy.
