Correct Answer: B

Rationale: The correct answer is 'Sagittal.' The sagittal plane divides the body into left and right halves, and movements in this plane involve flexion and extension. In this case, limited shoulder flexion on the left indicates a restriction in the forward and backward movement of the arm, which occurs in the sagittal plane.
Choice A, 'Horizontal,' is incorrect as it refers to movements parallel to the ground.
Choice C, 'Frontal,' is incorrect as it involves side-to-side movements.
Choice D, 'Vertical,' is incorrect as it typically refers to up and down movements.

Correct Answer: D

Rationale: The correct answer is respiratory alkalosis. In respiratory alkalosis, there is an elevated pH and low carbon dioxide levels (PaCO2 < 35 mmHg). In the given arterial blood gas reading, the patient's pH is 7.41 (within normal range), PaCO2 is 29 mmHg (below normal range), indicating respiratory alkalosis. The bicarbonate level is normal (25 mEq/l), ruling out metabolic acidosis or alkalosis. The low PaO2 (54 mmHg) may indicate hypoxemia, but it is not directly related to the acid-base disorder being assessed. Metabolic acidosis (choice
A) is characterized by low pH and low bicarbonate levels, which are not present in this case. Respiratory acidosis (choice
B) is indicated by low pH and high PaCO2 levels, which also do not match the provided data. Metabolic alkalosis (choice
C) is defined by high pH and high bicarbonate levels, which are not seen in this scenario.

Correct Answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice
B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice
C) involves the movement of solutes based on pressure gradients. Osmosis (choice
D) is the movement of water across a semipermeable membrane.

Correct Answer: B

Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (
Choice
A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (
Choice
C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (
Choice
D) should come after the initial assessment and vitals retake.

Correct Answer: A

Rationale: During a petit mal seizure, the highest priority is to provide a safe environment free of obstructions in the immediate area. This action aims to prevent injuries to the patient during the seizure. While calling a code or contacting the patient's physician may be necessary at some point, immediate safety measures take precedence. Preventing excessive movement of the extremities is relevant but ensuring a safe environment is crucial to avoid harm during the seizure.
