The prescription reads for guaifenesin 400 mg PO every 4 hours as needed for congestion. Using the label below, how many mL will the nurse administer to the client? Enter a numeric value only. Answer to the nearest whole mL.

The Correct Answer is ["20"]
1. Determine the concentration of the guaifenesin:
The label states 100 mg/5 mL.
2. Set up a proportion to find the volume (in mL) needed:
100 mg / 5 mL = 400 mg / x mL
3. Solve for x:
Cross-multiply: 100x = 400 * 5
100x = 2000
x = 2000 / 100
x = 20 mL
Answer: The nurse will administer 20 mL to the client.

Correct Answer is D
Explanation
A) Evaluation: Evaluation is the phase where the nurse assesses whether the goals or outcomes of the care plan have been met. It involves determining if the interventions provided were effective in achieving the desired outcomes. In this scenario, the nurse is still
gathering information before the action is taken, so evaluation is not the correct phase.
B) Planning: Planning is the phase in the nursing process where the nurse develops a care plan, which includes setting goals and determining interventions based on the client's needs. Although reviewing the medical record and blood glucose level is important for planning the administration of insulin, this is more about gathering data rather than forming a plan of care.
C) Implementation: Implementation refers to the actual delivery of the nursing interventions or actions. In this case, administering the insulin would be part of the implementation phase, but reviewing the medical history and obtaining a fingerstick blood glucose reading are steps taken before implementing the medication.
D) Assessment: The nurse is collecting pertinent information about the client’s condition, including reviewing the medical record and obtaining the blood glucose level. Assessment is the first step in the nursing process and involves gathering information to help guide clinical decisions.
E) Diagnosis: Diagnosis is the phase in which the nurse analyzes the assessment data to identify the client’s health problems or potential risks. While the nurse is collecting data, the diagnosis comes after the assessment phase, when the nurse has enough information to make a clinical judgment about the client's health status.
Correct Answer is B
Explanation
A) Ask the client what prescribed medications are taken at home: While obtaining information about the client's home medications is important, this action does not address the specific issue of the unclear order. It is not an appropriate substitute for clarifying the medication order that the nurse is having difficulty transcribing.
B) Contact the prescriber to clarify the order: This is the best action for the nurse to take. If the nurse is unsure about the order due to illegible handwriting, the safest and most effective way to clarify the order is to directly contact the prescriber. This ensures that the nurse administers the correct medication and dose, reducing the risk of medication errors.
C) Wait until the prescriber makes rounds again to clarify the order: Waiting for the prescriber to make rounds is not an appropriate or timely solution. Medication administration should not be delayed due to unclear orders, as it could lead to treatment delays or potential harm to the patient. Immediate clarification is necessary.
D) Ask a colleague what the order says: While consulting a colleague might be helpful, it is not the most reliable or safe course of action. The nurse should not rely on others to interpret unclear orders, as there may be different interpretations or misunderstandings. Contacting the prescriber directly ensures the order is clarified accurately and safely.
