A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available in potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

A.

10 mL/hr.

B.

50 mL/hr.

C.

100 mL/hr.

D.

500 mL/hr.

Answer and Explanation

The Correct Answer is C

Choice A rationale:
10 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 1 hour. However, the question asks for the rate at which to administer 10 mEq over 1 hour, which means the total volume should be 100 mL/hr.
Choice B rationale:
50 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 2 hours. However, the question specifies 1 hour, so the rate should be higher.
Choice C rationale:
This is the correct answer. To administer 10 mEq of potassium chloride in 100 mL over 1 hour, the infusion pump should be set to deliver 100 mL/hr.
Choice D rationale:
500 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 10 minutes (1/6th of an hour). However, the question specifies 1 hour, so the rate should be much lower.

Correct Answer is B

Explanation

Let's break down the calculation:

Given:

  • Patient weight: 154 lbs
  • Enoxaparin dosage: 0.75 mg/kg
  • Available enoxaparin: 60 mg/0.6 mL

Step 1: Convert pounds to kilograms:

  • 1 lb is approximately 0.4536 kg
  • So, 154 lbs = 154 * 0.4536 kg/lb = 69.85 kg (approximately 70 kg)

Step 2: Calculate the total dose of enoxaparin:

  • Desired dose = 0.75 mg/kg * 70 kg = 52.5 mg

Step 3: Determine the volume to administer:

  • We have enoxaparin 60 mg/0.6 mL
  • To find the volume for 52.5 mg:
    • (52.5 mg / 60 mg) * 0.6 mL = 0.525 mL
    • Rounded to the nearest tenth, this is 0.5mL.

Therefore, the nurse should administer 0.5mL of enoxaparin

Correct Answer is A

Explanation

Answer: A. Diplopia.

Rationale:

A) Diplopia: Diplopia, or double vision, is a common symptom in multiple sclerosis (MS) due to demyelination of nerves in the brainstem, affecting eye movement coordination. This visual disturbance is frequently seen in MS clients and may worsen during flare-ups.

B) Masklike expression: A masklike expression is more commonly associated with Parkinson’s disease rather than multiple sclerosis. This characteristic facial appearance is due to muscle rigidity, which is not typically a manifestation of MS.

C) Twitching of the face: Facial twitching, or fasciculations, is not typically a primary symptom of multiple sclerosis. While muscle weakness and spasticity are common in MS, twitching is more commonly seen in conditions such as amyotrophic lateral sclerosis (ALS).

D) Agitation: Agitation is not a primary symptom of MS. While MS can lead to cognitive changes or mood disturbances, such as depression, severe agitation is more commonly linked with other neurological or psychiatric conditions.
