A nurse is preparing to initiate IV therapy for a client.
Which of the following sites should the nurse use to place the peripheral IV catheter?

Dominant antecubital basilic vein.

Nondominant dorsal venous arch.

Dominant distal dorsal vein.

Nondominant forearm basilic vein

Answer and Explanation

The Correct Answer is D

This site is preferred for peripheral IV catheter placement because it is comfortable, has good blood flow, and has a lower risk of complications than the dominant arm or the antecubital fossa.

Choice A is wrong because the dominant antecubital basilic vein is more prone to dislodgement, thrombosis, and thrombophlebitis due to frequent movement of the elbow joint.

Choice B is wrong because the nondominant dorsal venous arch is a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.

Choice C is wrong because the dominant distal dorsal vein is also a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.

Correct Answer is B

Explanation

This is the recommended dosage for cyanocobalamin nasal spray for pernicious anaemia and vitamin B12 deficiency. Cyanocobalamin nasal gel is used to prevent a lack of vitamin B12 that may be caused by various factors.

Choice A is wrong because the duration of treatment depends on the individual’s response and blood levels of vitaminB. Some people may need to use this medication for longer than 6 months.

Choice C is wrong because there is no need to lie down for 1 hour after administering the medication.

This may cause nasal irritation or drainage.

Choice D is wrong because using a nasal decongestant 15 minutes before the medication may interfere with the absorption of cyanocobalamin. If you have a stuffy nose, you should talk to your doctor about alternative ways to take vitaminB.

A. Urine specific gravity 1.020. B. BUN 15 mg/dL. C. LDL 120 mg/dL. D. Blood glucose 90 mg/dL.

Correct Answer is C

Explanation

Atorvastatin is a medication that belongs to a group of drugs called statins. It is used to lower blood levels of “bad” cholesterol (low-density lipoprotein, or LDL), to increase levels of “good” cholesterol (high-density lipoprotein, or HDL), and to lower triglycerides (a type of fat in the blood). The treatment has been effective if the LDL level is reduced, as high LDL levels can increase the risk of heart disease and stroke. A normal range for LDL is less than 100 mg/dL.

Choice A is wrong because urine specific gravity is a measure of how concentrated the urine is, not how much cholesterol is in the blood. A normal range for urine specific gravity is 1.005 to 1.0304.

Choice B is wrong because BUN (blood urea nitrogen) is a measure of how well the kidneys are working, not how much cholesterol is in the blood. A normal range for BUN is 7 to 20 mg/dL.

Choice D is wrong because blood glucose is a measure of how much sugar is in the blood, not how much cholesterol is in the blood.

A normal range for blood glucose is 70 to 100 mg/dL.
