A nurse is preparing to administer esomeprazole 20 mg IV bolus in 100 mL 5% dextrose in water for a client who has peptic ulcer disease. Available is esomeprazole 40 mg/5 mL. How many milliliters should the nurse add to the 5% dextrose in water? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
Calculation:
Desired dose = 20 mg.
Available concentration = 40 mg / 5 mL
= 8 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 20 mg / 8 mg/mL
= 2.5 mL.

Correct Answer is D
Explanation
Rationale:
A. "I don't think you will benefit from reviewing your therapist's notes right now.": This statement dismisses the client’s request without addressing legal and policy guidelines regarding access to records. It also inappropriately assumes the client’s capacity to benefit from the information.
B. "Are you not happy with your treatment?": This redirects the conversation away from the request and implies dissatisfaction, which can create defensiveness. It does not provide the client with accurate information about their right to access medical records.
C. "Why are you interested in seeing your therapist's notes?": Asking “why” can sound confrontational and does not answer the client’s question. The focus should be on explaining what parts of the record can be shared, according to policy and law.
D. "We can provide a copy of your records, but the therapist's notes are not included.": Psychotherapy notes are excluded from standard medical record disclosures under HIPAA, as they are kept separate to protect sensitive details.
Correct Answer is D
Explanation
A. Decreased respirations: Moderate dehydration typically does not cause respiratory depression. Respiratory changes are more commonly associated with severe acid-base imbalances or advanced dehydration.
B. Polyuria: Dehydration leads to decreased fluid volume, which generally results in oliguria (reduced urine output) rather than polyuria. Increased urination is not an expected finding in moderate dehydration.
C. Bradycardia: Dehydration usually causes a compensatory increase in heart rate (tachycardia) to maintain cardiac output. Bradycardia is not typical unless there is a severe or underlying cardiac issue.
D. Orthostatic hypotension: Loss of fluid volume from diarrhea and vomiting can decrease circulating blood volume, leading to a drop in blood pressure upon standing. This is an expected cardiovascular manifestation of moderate dehydration in school-age children.
