Correct Answer: A

Rationale: Communicating the colleague's actions to the unit charge nurse is the most appropriate action to take in this scenario. Reporting to the charge nurse follows proper protocol and ensures privacy compliance. This option allows for addressing the issue internally within the healthcare setting, maintaining confidentiality, and following the chain of command. Sending an email to facility administration (Choice B) might be premature without internal investigation and could potentially bypass the immediate supervisor who is responsible for addressing such issues. Writing an anonymous complaint to a professional website (Choice C) and posting a comment about the action on a staff discussion board (Choice D) are not professional or effective ways to address the situation, as they do not ensure proper handling of the breach of privacy within the organization.

Correct Answer: B

Rationale: The correct action when assessing an immobile patient for deep vein thromboses (DVTs) is to measure the calf circumference of both legs. This helps in detecting swelling or changes that may indicate the presence of a DVT. Removing elastic stockings every 4 hours (Choice A) is not necessary and can disrupt circulation. Lightly rubbing the lower leg for redness and tenderness (Choice C) can potentially dislodge a clot if present. Dorsiflexing the foot while assessing for patient discomfort (Choice D) is not a specific assessment for DVT and may not provide relevant information in this context.

Correct Answer: D

Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.

Correct Answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.
