Which of the ff signs may be revealed by a visual examination in a client with tonsillar infection if group A streptococci is the cause?

Correct Answer: A

Rationale: The presence of white patches on the tonsils is a visual sign that may be revealed by a visual examination in a client with a tonsillar infection caused by group A streptococci. These white patches are known as exudates and can be a characteristic feature of streptococcal tonsillitis. These exudates may range in appearance from small white spots to larger patches that cover the tonsils. Additionally, other signs commonly associated with streptococcal tonsillitis may include swollen and red tonsils, fever, sore throat, and sometimes swollen lymph nodes in the neck. It is important to note that definitive diagnosis often requires laboratory testing such as a rapid strep test or throat culture to confirm the presence of group A streptococci.

Correct Answer: C

Rationale: The major manifestation of nephrotic syndrome is edema. Nephrotic syndrome is a kidney disorder characterized by increased permeability of the glomerular filtration barrier, leading to excessive protein loss in the urine. This results in low levels of protein in the blood, particularly albumin, leading to a decrease in oncotic pressure. The decreased oncotic pressure causes fluid to accumulate in the interstitial spaces, leading to edema formation. Patients with nephrotic syndrome typically present with periorbital edema, pedal edema, and ascites due to the fluid redistribution in the body. Hematuria, hyperalbuminemia, and anemia are not typically the primary manifestations of nephrotic syndrome.

Correct Answer: D

Rationale: Oxygen desaturation of 2-30% is too low to define mild-to-moderate sleep apnea.

Correct Answer: C

Rationale: The nurse should include in the teaching that the parent will need to avoid adding salt to the child's food. This is important because reducing salt intake helps to decrease fluid retention and swelling in the body, which is critical for managing edema associated with acute glomerulonephritis. Excessive salt intake can worsen edema by causing the body to retain more fluid, so it is crucial to limit salt in the child's diet. This dietary modification can help improve the child's condition and overall health outcome.

Correct Answer: B

Rationale: The majority of lumbar disc herniations occur at the level of L4-L5. This is because the L4-L5 disc segment bears the highest amount of stress and load in the lumbar spine due to its location and mechanics. The intervertebral disc between the fourth (L4) and fifth (L5) lumbar vertebrae is subject to repetitive movements and mechanical stress, making it more susceptible to herniation compared to other levels in the lumbar spine. Additionally, the anatomy of the L4-L5 disc makes it more prone to degeneration and herniation, leading to a higher prevalence of herniated discs at this level.
