The nurse is caring for a patient who has experienced a laparoscopic appendectomy. For which type of healing will the nurse focus the care plan?

Primary Intention

Partial-thickness repair

Secondary Intention

Tertiary intention

Answer and Explanation

The Correct Answer is A

A. Primary Intention: Primary intention healing occurs when surgical incisions are closed with sutures, staples, or adhesive strips. Since laparoscopic procedures involve small incisions that are closed immediately, this type of healing applies.

B. Partial-thickness repair: Partial-thickness repair refers to wounds that involve only the epidermis and part of the dermis (e.g., abrasions, minor burns). Surgical incisions are full-thickness wounds, so this is not applicable.

C. Secondary Intention: Secondary intention healing occurs when wounds heal from the inside out, typically seen in pressure ulcers, large open wounds, or infected wounds. Surgical wounds that are sutured do not heal by secondary intention.

D. Tertiary Intention: Tertiary intention healing occurs when a wound is left open initially and later closed due to infection risk or delayed healing. Laparoscopic appendectomy wounds are closed immediately, making this choice incorrect.

Correct Answer is B

Explanation

A. AV Node: The AV node is responsible for delaying electrical impulses before they pass to the ventricles, but it does not generate the P wave. It affects the PR interval rather than the P wave itself.

B. SA Node: The SA (sinoatrial) node initiates electrical impulses and is responsible for atrial depolarization, which produces the P wave on an ECG. This makes it the correct answer.

C. Purkinje Fibers: The Purkinje fibers play a role in ventricular contraction (QRS complex), not in the formation of the P wave.

D. Bundle of HIS: The Bundle of HIS transmits impulses to the ventricles and is involved in ventricular depolarization, not atrial activity. It is not responsible for the P wave.

A. Hold her breath for at least 10 seconds. B. Place her hands on the sides of her rib cage. C. Exhale forcefully through the nose. D. Inhale slowly and evenly through her nose.

Correct Answer is D

Explanation

A. Hold her breath for at least 10 seconds. Diaphragmatic breathing focuses on slow, deep breaths to promote lung expansion and oxygenation. Holding the breath is not part of this technique and may increase discomfort.

B. Place her hands on the sides of her rib cage. While hand placement is encouraged, the correct position is on the abdomen (below the rib cage), not the sides. This helps the client feel the diaphragm expanding.

C. Exhale forcefully through the nose. Exhalation should be slow and controlled through the mouth, not forceful through the nose, to prevent airway irritation.

D. Inhale slowly and evenly through her nose. The correct technique for diaphragmatic breathing is to inhale deeply through the nose while the abdomen expands. This promotes lung expansion and prevents atelectasis postoperatively.
