Question 2 of 5
An adult is admitted to the hospital with several days of vomiting and diarrhea. Admitting data show RBC level of 4.2 million/mm³ and hematocrit of 54%. What is the best interpretation of these data?
Correct Answer: B
Rationale: Elevated hematocrit (normal: 36-46% for females, 41-53% for males) with normal RBC suggests hemoconcentration from dehydration due to fluid loss from vomiting and diarrhea.
Question 3 of 5
A client comes to the emergency department reporting alkaline drain cleaner splashed into the eye. The conjunctiva of the affected eye is erythematous, and the client reports a burning sensation. What action is appropriate at this time?
Correct Answer: C
Rationale: Ocular chemical burns require emergency care to prevent permanent vision loss. Alkali burns (eg, ammonia, cement, lye- containing drain cleanser) are particularly dangerous as they will quickly penetrate deep into the eye, causing severe, irreversible damage. For all types of ocular chemical burns, copious eye irrigation with sterile saline or water should begin immediately to flush the chemical irritant out of the eye
Question 4 of 5
The home health nurse reviews the serum laboratory test results for a client with seizures. The phenytoin level is 27 mcg/mL. The client makes which statement that may indicate the presence of dose-related drug toxicity and prompt the nurse to notify the supervisory registered nurse?
Correct Answer: A
Rationale: A phenytoin level of 27 mcg/mL is above the therapeutic range (10-20 mcg/mL), indicating potential toxicity. Unsteadiness when walking suggests neurological toxicity, such as ataxia, which requires immediate reporting. Nocturia, metallic taste, and gingival hyperplasia are less urgent or unrelated.
Question 5 of 5

Correct Answer: A
