A nurse is preparing to administer potassium chloride 20 mEq. The amount available is potassium chloride liquid 40 mEq/15 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["7.5"]

We can calculate the volume of potassium chloride solution to administer using the following steps:

Identify the prescribed dose: The nurse needs to administer 20 mEq of potassium chloride.

Identify the concentration of available solution: The potassium chloride liquid is available in a concentration of 40 mEq/15 mL. This means there are 40 milliequivalents (mEq) of potassium chloride in every 15 milliliters (mL) of the solution.

Set up a proportion to find the volume needed:

Desired dose (mEq) : Volume to administer (mL) = Concentration (mEq/mL)

Plug in the values:

20 mEq : Volume to administer (mL) = 40 mEq/15 mL

Solve for the volume:

To isolate the volume (mL), multiply both sides of the proportion by the volume unit (mL) and divide by the dose (mEq).

Volume to administer (mL) = (20 mEq) x (mL) / (40 mEq/15 mL)

We can simplify the calculation before dividing:

Volume to administer (mL) = (20 mEq x 15 mL) / 40 mEq

Volume to administer (mL) = 300 mL / 40 mEq

Volume to administer (mL) = 7.5 mL (round to one decimal place)

Therefore, the nurse should administer 7.5 mL of the potassium chloride solution.

Correct Answer is D

Explanation

A) Dyspnea:
Diphenhydramine primarily addresses allergic reactions such as urticaria (hives) rather than respiratory symptoms like dyspnea associated with blood transfusion reactions.

B) Fever:
The administration of diphenhydramine during blood transfusions is aimed at mitigating allergic reactions, particularly urticaria, rather than fever as a symptom.

C) Low-back pain:
Diphenhydramine is not indicated for preventing or managing low-back pain, which is not typically associated with allergic reactions to blood transfusions.

D) Urticaria:
Diphenhydramine is administered to prevent or reduce symptoms of allergic reactions, particularly urticaria (hives), which can occur during blood transfusions due to immune responses to transfused blood components.

A. Relief from constipation B. Decreased cancer pain C. Decreased drowsiness D. Relief from nausea

Correct Answer is A

Explanation

A) The client should use an electric razor while on this medication:
Warfarin is an anticoagulant that increases the risk of bleeding. Using an electric razor instead of a manual razor reduces the risk of cuts and bleeding while shaving, which is important to minimize bleeding complications associated with warfarin therapy.

B) Warfarin increases the risk for deep vein thrombosis:
Warfarin actually decreases the risk of deep vein thrombosis (DVT) and other blood clotting disorders by inhibiting the production of clotting factors. It is used to prevent and treat blood clots, not increase their risk.

C) Nose bleeds are common during initial treatment:
While bleeding is a potential side effect of warfarin therapy, nosebleeds specifically are not more common during initial treatment compared to later phases of therapy. Any bleeding should be reported to the healthcare provider for assessment and management.

D) If he misses a dose, he should double the dose at the next scheduled time:
Doubling the dose of warfarin can increase the risk of bleeding due to excessive anticoagulation. If a dose is missed, the client should take it as soon as they remember unless it is close to the time for the next scheduled dose, in which case they should skip the missed dose and continue with the regular schedule.
