The nurse calculates that 0.74 mi of filgrastim must be administered to a client subcutaneously. The client weights 165 lbs. What length and gauge of needle is best to administer this medication?

2 inches 21 gauge

1 1/2 inch 27 gauge

5/8 inch 25 gauge

1/4 inch 19 gauge

Answer and Explanation

The Correct Answer is C

A. 2 inches 21 gauge: This option is too long and too large in gauge for subcutaneous administration. Typically, a longer needle is not necessary for subcutaneous injections, especially for standard adult adipose tissue.

B. 1 1/2 inch 27 gauge: While this gauge is acceptable, the length is still longer than typically required for subcutaneous injections. A 1 1/2 inch needle is more suited for intramuscular injections.

C. 5/8 inch 25 gauge: This is the most appropriate choice for a subcutaneous injection. A 5/8 inch needle is typically adequate for subcutaneous tissue in adults, and a 25 gauge needle provides a suitable size for comfort while allowing the medication to be administered effectively.

D. 1/4 inch 19 gauge: This option is not suitable for subcutaneous injections. A 1/4 inch length is too short for effective penetration into subcutaneous tissue, and a 19 gauge needle is larger than necessary, which could increase discomfort.

Correct Answer is B

Explanation

A. Increase calcium in the diet: While calcium is important, it's not the most critical aspect in managing hypertension compared to weight management.

B. Monitor weight on a weekly basis: Weight management is crucial for clients with hypertension, as fluctuations can indicate changes in fluid retention or overall health. Regular monitoring can help in managing blood pressure.

C. Obtain blood pressure checks twice a year: This is insufficient for monitoring hypertension; more frequent checks are generally recommended.

D. Have yearly eye examinations: While important for overall health, it’s not as directly related to the management of hypertension as monitoring weight.

A. Furosemide 40 mg PO daily for a client whose blood pressure is 123986. B. Nitroglycerin 0.4 mg SL PRN for a client complaining of chest C. Metoprolol 25 mg PO bid for a client whose heart rate is 55 beats D. Diltiazem 30 mg PO tid for a client whose heart rate is 90 beats/min

Correct Answer is B

Explanation

A) Furosemide 40 mg PO daily for a client whose blood pressure is 123/86: While furosemide is important for managing fluid status, the client's blood pressure is within a normal range, and this medication does not address any acute concerns.

B) Nitroglycerin 0.4 mg SL PRN for a client complaining of chest pain: This prescription should be implemented first because it addresses an immediate and potentially life-threatening symptom. Chest pain can indicate angina or myocardial infarction, making it critical to relieve this symptom promptly.

C) Metoprolol 25 mg PO bid for a client whose heart rate is 55 beats: While metoprolol is important for managing heart rate and hypertension, a heart rate of 55 beats/minute is on the lower end and could warrant caution. The priority would be to assess the need for medication before administering it.

D) Diltiazem 30 mg PO tid for a client whose heart rate is 90 beats/min: This medication is also important for managing heart rate and hypertension but is not the priority over addressing acute chest pain. The client’s heart rate is within a normal range, so this does not require immediate action compared to the nitroglycerin for chest pain.
