A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/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.)

A. Inverted P wave: An inverted P wave may indicate atrial depolarization abnormalities but is not typically associated with hypokalemia. It can be seen in conditions such as atrial enlargement or atrial ischemia. However, in hypokalemia, the P wave may become flattened or have a decreased amplitude, but it is less likely to be inverted.
B. Wide QRS: A wide QRS complex may indicate conduction abnormalities or bundle branch blocks, but it is not specifically associated with hypokalemia. Wide QRS complexes are more commonly seen in conditions such as bundle branch blocks or electrolyte imbalances like hyperkalemia. Hypokalemia tends to cause a prolongation of the QT interval rather than widening of the QRS complex.
C. Elevated ST segment: An elevated ST segment is typically associated with myocardial injury or infarction, not hypokalemia. It can be indicative of conditions such as myocardial ischemia or pericarditis. In hypokalemia, ST segment changes are more likely to be flattened or depressed rather than elevated.
D. Abnormally prominent U wave: An abnormally prominent U wave is a classic EKG finding in hypokalemia. Hypokalemia prolongs the repolarization phase of the cardiac action potential, leading to the appearance of U waves following the T wave. These U waves can become more pronounced as potassium levels decrease. Therefore, an abnormally prominent U wave is a significant indicator of hypokalemia on an EKG, especially in a patient with prolonged vomiting, which can lead to potassium depletion. Thus, it is the most pertinent abnormality to interpret in this context.

Sharing personal passwords for accessing electronic client records is a violation of healthcare privacy and security regulations, such as the Health Insurance Portability and Accountability Act (HIPAA). Personal passwords should never be shared with anyone, regardless of their role or position within the healthcare facility. Each individual accessing electronic records should have their own unique login credentials to maintain accountability and protect the confidentiality of client information.
A. The nurse manager: While the nurse manager may have legitimate reasons to access client records, they should do so using their own authorized credentials. Sharing passwords compromises security and accountability.
B. A nursing student who is completing a preceptorship on the unit: Nursing students should be provided with their own temporary login credentials or supervised access to client records as part of their educational experience. Sharing personal passwords with students is inappropriate and violates privacy regulations.
C. The unit clerk: Unit clerks may require access to certain client information for administrative purposes, but they should have their own authorized login credentials provided by the facility. Sharing passwords with non-clinical staff like unit clerks poses risks to client privacy and confidentiality.
D. No one: This option is the correct choice. Personal passwords should never be shared with anyone, as doing so compromises security, violates privacy regulations, and undermines accountability for accessing electronic client records.
