Question

A nurse is talking with a client who is scheduled for surgery to repair retinal detachment. Which of the following preoperative instructions should the nurse include?

Answer 1

Correct Answers:

Restrict head movement.

Rationale :

✅ Prior to surgery for retinal detachment, the client must be instructed to restrict head and eye movement to prevent further retinal separation.

✅ Retinal detachment involves the separation of the retina from the underlying tissue, and any sudden or excessive movement may worsen the detachment or cause additional retinal tearing.

✅ Immobilization helps maintain the retina's position, reducing intraocular pressure and preventing vitreous shifting.

✅ Unlike the application of cool compresses or patching both eyes, head restriction is critical in stabilizing the retina until surgical repair is performed.

✅ Eye drops used in retinal detachment cases typically dilate the pupil (mydriatics) rather than constrict it to facilitate surgical access.

Answer 2

Correct Answers:

Glucagon treats hypoglycemia resulting from insulin overdose.

Rationale :

🔹Glucagon is an emergency medication used to treat severe hypoglycemia, especially in clients with type 1 diabetes mellitus who are unable to safely consume carbohydrates due to unconsciousness or seizures.

🔹It works by stimulating the liver to convert stored glycogen into glucose, thereby rapidly increasing blood glucose levels.

🔹This is particularly useful in the event of insulin overdose, skipped meals, or increased physical activity without proper insulin adjustment.

🔹 Families of children with diabetes should be taught to administer glucagon intramuscularly or subcutaneously and seek emergency assistance afterward.

🔹 Glucagon is not used to enhance insulin effects or treat lipoatrophy.

Answer 3

Correct Answers:

The most common cause of a cataract is aging-

Rationale :

🔹Cataracts are characterized by the clouding of the lens, which interferes with light transmission and impairs vision.

🔹The most common cause is the natural aging process, in which lens proteins degrade and clump together, resulting in opacities.

🔹This condition is termed senile cataracts and typically occurs in adults over 60.

🔹Risk factors such as ultraviolet light exposure, smoking, diabetes, and long-term corticosteroid use can accelerate this process.

🔹While trauma or congenital factors may contribute in younger populations, age-related degeneration remains the predominant cause in older adults, and understanding this helps guide prevention and screening.

Answer 4

Correct Answers:

"It is hypertension with no specific cause!'

Rationale :

◑ Primary hypertension, also referred to as essential hypertension, is diagnosed when no identifiable secondary cause is found.

◑ It accounts for the vast majority (90–95%) of hypertension cases.

◑ This form of hypertension develops gradually due to a combination of genetic predisposition, lifestyle factors (e.g., high sodium intake, obesity, sedentary behavior), and age-related vascular changes.

◑ The term does not imply severity or urgency but rather indicates that it is not caused by another disease, such as renal artery stenosis or endocrine disorders.

◑ Education should focus on lifestyle modifications and long-term pharmacologic control to prevent complications such as stroke, heart failure, and kidney disease.

Answer 5

Correct Answers:

Take prescribed anti-inflammatory medications with meals.

Rationale :

⇛ Clients with rheumatoid arthritis (RA) are commonly prescribed nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids to reduce joint inflammation and improve function.

⇛ These medications are gastric irritants, especially with long-term use, and can lead to gastritis, ulcers, or gastrointestinal bleeding if taken on an empty stomach.

⇛ Clients must be instructed to take these medications with food or milk to reduce the risk of adverse gastrointestinal effects.

⇛ While other options such as alternating hot and cold packs and avoiding high-impact activity are also helpful, NSAID safety is a critical component of medication adherence and long-term therapy effectiveness.

Answer 6

Correct Answers:

Pruritus

Rationale :

🔹Scabies is a contagious skin condition caused by infestation with the mite Sarcoptes scabiei.

🔹The primary clinical manifestation is intense pruritus (itching), which is especially severe at night.

🔹The itching results from a delayed hypersensitivity reaction to the mites, their eggs, and feces within the skin.

🔹 The rash may present as small papules, burrows, or vesicles, commonly located between the fingers, wrists, elbows, and along the waistline.

🔹Persistent scratching can lead to secondary bacterial infections, particularly in children.

🔹Recognizing pruritus as the hallmark symptom supports early diagnosis and effective treatment with topical scabicides.

Answer 7

Correct Answers:

Preventing infection of lesions.

Rationale :

💎In infants with eczema (atopic dermatitis), maintaining skin integrity is essential due to the risk of secondary bacterial infection, particularly from scratching open lesions.

💎Preventing infection becomes the top priority, especially in infants with immature immune systems.

💎Nursing interventions include moisturizing the skin, keeping fingernails trimmed, using hypoallergenic products, and monitoring for signs of infection (e.g., pus, increased redness, warmth).

💎Keeping the infant content and ensuring nutrition are also important, but infection control takes priority to prevent complications like cellulitis or systemic infection.

Answer 8

Correct Answers:

Fatigue. night sweats, and hemoptysis

Rationale :

✔️ The classic clinical presentation of active tuberculosis (TB) includes chronic fatigue, night sweats, low-grade fever, weight loss, and productive cough with possible hemoptysis.

✔️ These symptoms develop gradually and reflect progressive pulmonary involvement caused by Mycobacterium tuberculosis.

✔️ Hemoptysis occurs due to erosion of blood vessels in necrotic lung tissue.

✔️ Night sweats and fatigue result from the chronic inflammatory response.

✔️ Recognizing this constellation of symptoms supports early diagnosis, airborne isolation, and initiation of multidrug antitubercular therapy to prevent spread and complications.

Answer 9

Correct Answers:

Potassium

Rationale :

🔸Thiazide diuretics, such as hydrochlorothiazide, increase the excretion of sodium, chloride, and potassium in the distal renal tubules.

🔸 This results in potassium depletion, which can cause muscle weakness, fatigue, and potentially fatal cardiac arrhythmias.

🔸Therefore, clients are advised to consume potassium-rich foods (e.g., bananas, oranges, spinach) or may be prescribed potassium supplements.

🔸Unlike loop diuretics, thiazides may slightly increase calcium levels, and there is no significant loss of sodium or magnesium to warrant supplementation unless otherwise indicated.

Answer 10

Correct Answers:

Apply a thin layer of cream and rub it into the area thoroughly.

Rationale :

✔️Topical corticosteroids are prescribed to reduce inflammation in conditions like contact dermatitis, but must be used judiciously in children due to increased percutaneous absorption and potential systemic effects.

✔️ Parents should be instructed to apply a thin layer only to the affected area, and to gently rub it in until absorbed.

✔️ Overuse or application to large areas can lead to side effects like skin atrophy, pigmentation changes, or adrenal suppression.

✔️ Cleansing the area before application is generally recommended, and the medication should not be applied thickly or to unaffected skin.
