An intravenous (IV) antibiotic is prescribed for a client with a postoperative infection. The medication is to be administered in 4 divided doses. Which schedule is best for administering this prescription?

Administer with meals and a bedtime snack.

1000, 1600, 2200, 0400.

0800, 1200, 1600, 2000.

Give in equally divided doses during waking hours.

Answer and Explanation

The Correct Answer is C

A.   Administer with meals and a bedtime snack. This schedule does not ensure that the medication is administered at equally spaced intervals throughout the day, as required for 4 divided doses.
B.   1000, 1600, 2200, 0400. This schedule is not practical or feasible, as it includes a dose in the middle of the night.
C.   0800, 1200, 1600, 2000. This schedule provides equally divided doses at intervals that are practical and coincide with the client's waking hours.
D.   Give in equally divided doses during waking hours. While this option mentions administering doses during waking hours, it does not specify specific times for administration, unlike option C.

Correct Answer is C

Explanation

A. BRCA1 and BRCA2 provide protection of mature, functioning breast and ovarian cells. This is not accurate; BRCA1 and BRCA2 genes are involved in DNA repair, and mutations in these genes increase cancer risk.
B. The choice of treatment is best determined by the sensitivity of these genetic markers. While genetic markers can influence treatment decisions, this option does not directly address the role of BRCA1 and BRCA2 mutations in cancer risk.
C. Mutations in BRCA1 or BRCA2 identify a client's risk for cancerous cell development in breast tissue. This is correct. Mutations in these genes significantly increase the risk of developing breast and ovarian cancer.
D. The prognosis of breast cancer is most successful when these markers are inherited mutations.
This statement is incorrect. The presence of BRCA1 or BRCA2 mutations influences risk, not necessarily prognosis or treatment success.

A. Humidifier bottle B. Lamb's wool C. Flowmeter D. Tape E. Suction cannister F. Nasal cannula G. Sterile water

Correct Answer is ["A","C","F","G"]

Explanation

A. Humidifier bottle

Rationale: A humidifier bottle is often used with oxygen therapy to add moisture to the oxygen, preventing dryness of the nasal passages and throat. It is important for patient comfort, especially when oxygen is administered at higher flow rates for prolonged periods.

B. Lamb's wool

Rationale: Lamb's wool is not needed for starting oxygen therapy. It is typically used to provide padding and comfort in other situations, such as preventing pressure sores, but it has no role in the administration of oxygen.

C. Flowmeter

Rationale: A flowmeter is necessary to regulate the flow rate of oxygen. It ensures that the client receives the prescribed amount of oxygen (3 L/minute in this case), making it an essential component for administering oxygen therapy.

D. Tape

Rationale: Tape is not required for administering oxygen via a nasal cannula. It might be used to secure tubing in other contexts, but it is not specifically needed for starting oxygen therapy. The nasal cannula usually stays in place without the need for tape.

E. Suction cannister

Rationale: A suction canister is used in suctioning procedures to collect secretions and is not needed for starting oxygen therapy. It is relevant for managing airway secretions but unrelated to the administration of oxygen.

F. Nasal cannula

Rationale: A nasal cannula is the device through which oxygen is delivered to the client. It is specifically mentioned in the order and is essential for administering the oxygen.

G. Sterile water

Rationale: Sterile water is used to fill the humidifier bottle to provide humidified oxygen. This helps to prevent the drying effects of oxygen therapy on the mucous membranes, enhancing patient comfort.
