Blood is what kind of solution?

None

Hypertonic

Isotonic

Hypotonic

Answer and Explanation

The Correct Answer is C

Rationale-Blood is considered an isotonic solution because its solute concentration is similar to that of the cells in the body, allowing for free movement of water across cell membranes without causing a net influx or efflux of water. This isotonic nature is crucial for maintaining cell integrity and function.

Isotonic solutions have the same osmotic pressure as body’s plasma

B-Hypertonic solution like 3% saline have higher osmotic pressure compared to plasma. This type of solutions draw water from the cells causing shrinkage

D-Hypotonic solution like 0.45% saline have lower osmotic pressure as compared to plasma. They cause swelling of cells with eventual damage

Correct Answer is D

Explanation

Morphine is an opioid medication used to treat moderate to severe pain but comes with a list of contraindications where its use would be inappropriate or dangerous.

A-A myocardial infarction, commonly known as a heart attack, is not a contraindication for morphine; in fact, morphine can be used to relieve pain associated with heart attacks.

B-Postoperative pain management following hip arthroplasty often includes opioids like morphine, unless specific contraindications are present.

C-While morphine can affect respiratory function, bronchitis pleurisy is not listed as a direct contraindication. However, caution is advised due to the potential for respiratory depression.

D-Paralytic ileus, a condition of obstructed bowel without any mechanical cause, is a contraindication for morphine use because opioids can exacerbate the condition by slowing down intestinal motility, leading to increased risk of significant complications.

A. Omit the KCL dose and document that it was not given. B. Hold the prescribed dose and notify the provider of the serum potassium level. C. Give the ordered KCL as prescribed. D. Call the lab to verify the client's results.

Correct Answer is C

Explanation

A serum potassium level of 3.2 mEq/L is considered low, as normal potassium levels are typically between 3.5 and 5.0 mEq/L. When a client has hypokalemia (low potassium), administering potassium chloride (KCl) can help to correct the imbalance. It is important for the nurse to follow hospital protocols and guidelines when administering medications, especially those that can affect electrolyte balance.

A-Holding the KCL in inappropriate as it is needed from the indicated levels

B-The KCL should not be held as the client needs it

D-Hypokalemia is expected in loop diuretics therapy due to renal losses of potassium
