Blood is what kind of solution?
None
Hypertonic
Isotonic
Hypotonic
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 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
Correct Answer is A
Explanation
Morphine sulfate, an opioid analgesic, can cause serious side effects including lifethreatening respiratory depression. A normal respiratory rate for adults is typically between 12 to 16 breaths per minute. A rate of 8 breaths per minute is considered abnormally low and can be indicative of respiratory depression, which is a serious risk associated with opioid medications like morphine sulfate. It's important for healthcare providers to monitor clients closely after administering opioids to manage any potential adverse effects promptly.
B-SaO2 is not a direct indicator of central respiratory depression
C-Pain relief is expected as it is an analgesic
D-Morphine can cause sedation which is okay after respiratory depression has been ruled out
