Question 1 of 5
The nurse administered phenylephrine eye drops to the client before performing an ophthalmoscopic eye examination. Which assessment finding should the nurse expect?
Correct Answer: D
Rationale: A: Tremors are a side effect if phenylephrine is absorbed systemically. B: Because phenylephrine absorbed systemically is a vasoconstrictor, hypertension (not hypotension) can occur as a side effect. C: Miosis is pupil constriction, not an effect of phenylephrine. D: Phenylephrine (NeoSynephrine), an adrenergic agonist, produces pupil dilation (mydriasis) by activating alpha1-adrenergic receptors on the dilator muscles of the iris.
Question 2 of 5
The client with CP is taking dantrolene. The nurse evaluates that the medication is effective when noting that the client has an increase in which findings? Select all that apply.
Correct Answer: C,D
Rationale: A: Increased muscle spasticity indicates the medication is not effective. B: Common adverse effects include urinary frequency. C: Dantrolene acts directly on skeletal muscles to inhibit muscle contraction, improving mobility. D: Dantrolene acts directly on skeletal muscles to inhibit muscle contraction, improving the ability to maintain balance. E: Dantrolene does not increase alertness.
Question 3 of 5
The nurse is performing a health history on the child with ADHD who is being evaluated for treatment with psychostimulants. Which information is most critical to collect prior to treatment with psychostimulants?
Correct Answer: D
Rationale: Cardiovascular history is critical due to contraindications of psychostimulants in certain CV conditions.
Question 4 of 5
The nurse working on the pediatric unit has scheduled medications to administer at this time. Which assessments should prompt the nurse to conclude that the prescribed medication should be withheld and the HCP immediately notified?
Correct Answer: C
Rationale: A: Dizziness and light-headedness are side effects of hydrocodone with acetaminophen (Vicodin), and the nurse may choose to withhold a scheduled dose. These are not potentially life-threatening or warranting an immediate call to the HCP. B: A rash is a side effect of acetaminophen (Tylenol). However, the rash is not potentially life-threatening or warranting an immediate call to the HCP. C: An adverse effect of clindamycin (Cleocin) is hypotension. A BP of 92/56 mm Hg is low for a 16-year-old. Normal BP for a 16-year-old male is 111/63 mm Hg to 136/90 mm Hg, depending on height percentile. The nurse should compare the previous BP readings with the current one to determine the degree of BP variation and then immediately notify the HCP because the BP can decrease further. D: Tiredness and drowsiness are side effects of phenobarbital (Luminal). However, these are expected. The nurse would not withhold phenobarbital unless there were additional neurological alterations that would warrant contacting the HCP.
Question 5 of 5
The nurse is preparing to administer Azithromycin, and the pharmacy has provided the drug in a powder form that requires reconstitution connected to a saline piggyback. Which of the following is least concerning when preparing the medication?
Correct Answer: B
Rationale: The brand or trade name is not required to be on the medication label if the generic name is present. The nurse should check that the medication is not expired and that it has been stored according to the storage instructions. If the saline bag is leaking, it may indicate that the container is damaged and the fluid may not be sterile.
