A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose?
(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"]

To calculate the amount of potassium chloride elixir needed per dose, we can use the following formula:

Amount per dose (mL) = (Desired dose in mEq / Concentration in mEq/mL) * Volume in mL

Given:

Desired dose = 20 mEq/day divided equally every 12 hr = 10 mEq/dose

Concentration = 6.7 mEq/5 mL

Plugging in the values:

Amount per dose (mL) = (10 mEq / 6.7 mEq/5 mL) * 5 mL

Calculating:

Amount per dose (mL) ≈ 7.46 mL

Rounded to the nearest tenth, the nurse should administer approximately 7.5 mL of the potassium chloride elixir per dose.

Correct Answer is A

Explanation

A. Increased respiratory rate.
Naloxone is an opioid receptor antagonist used to reverse the effects of opioids like morphine. When administered to a client who has developed an adverse reaction to morphine, naloxone can rapidly reverse the effects of opioid overdose, including respiratory depression. Therefore, an increased respiratory rate is a therapeutic effect of naloxone, as it helps restore normal breathing patterns in clients who are experiencing respiratory depression due to opioid overdose.
B. Decreased blood pressure: Naloxone is not primarily used to affect blood pressure. Its primary goal is to reverse opioid overdose effects, particularly respiratory depression.
C. Increased pain relief: Naloxone does not directly increase pain relief. Its primary action is to reverse the effects of opioids at the receptor sites, which can also lead to the reduction of pain relief provided by opioids. However, its main role is the reversal of opioid overdose effects, not enhancing pain relief.
D. Decreased nausea: Nausea is a common side effect of opioid use. While naloxone can help reverse opioid overdose effects, it does not necessarily directly address nausea. Its main purpose is to restore normal respiratory function in cases of opioid overdose.

A. "Decrease your daily sodium intake." B. "Take this medication 2 hours before a meal." C. "Limit foods containing tyramine." D. "Report swelling of the feet to your provider."

Correct Answer is D

Explanation

A. "Decrease your daily sodium intake."
Incorrect Explanation: This instruction is appropriate for a client taking lithium carbonate.
Explanation: Lithium is a mood-stabilizing medication commonly prescribed for conditions like bipolar disorder. High levels of sodium can lead to increased lithium retention in the body, potentially raising the risk of toxicity. Advising the client to decrease their daily sodium intake helps prevent this.
B. "Take this medication 2 hours before a meal."
Incorrect Explanation: This instruction is not accurate for lithium carbonate.
Explanation: Lithium carbonate is typically taken with food or milk to help minimize stomach upset. Taking it on an empty stomach might increase the risk of gastrointestinal side effects.
C. "Limit foods containing tyramine."
Incorrect Explanation: This instruction is not directly relevant to lithium carbonate.
Explanation: Tyramine is a compound found in some foods and can interact with certain medications like monoamine oxidase inhibitors (MAOIs), but it is not a primary concern with lithium carbonate.
D. "Report swelling of the feet to your provider."
Correct Explanation: This instruction is appropriate for a client taking lithium carbonate.
Explanation: Lithium can lead to water retention, which might result in swelling, particularly in the feet and ankles. Reporting swelling is important as it can be an early sign of potential side effects or changes in kidney function.
