A patient presents with acute onset of shoulder pain and limited range of motion after a fall onto an outstretched hand. Physical examination reveals tenderness over the greater tuberosity of the humerus and pain with passive abduction and external rotation of the shoulder. Which of the following conditions is most likely?

Correct Answer: A

Rationale: The correct answer is A: Rotator cuff tear. The presentation of acute shoulder pain and limited range of motion after a fall onto an outstretched hand, along with tenderness over the greater tuberosity and pain with passive abduction and external rotation, is classic for a rotator cuff tear. The mechanism of injury and physical exam findings are consistent with this condition. B: Glenohumeral dislocation typically presents with a visibly deformed shoulder and loss of normal shoulder contour. C: Acromioclavicular joint separation would present with tenderness over the AC joint rather than the greater tuberosity, and typically involves a history of direct trauma to the shoulder. D: Proximal humerus fracture would present with more diffuse shoulder pain and swelling, and not specific tenderness over the greater tuberosity.

Correct Answer: A

Rationale: The correct answer is A because zero absenteeism and tardiness of pupils indicate that the school nursing programs are effectively promoting student health and well-being. This outcome shows that students are healthy, engaged, and present in school, which is a key goal of school nursing initiatives. Choice B is incorrect as teachers being observers does not directly measure the effectiveness of the nursing programs. Choice C is incorrect as limited information hinders the success and impact of school health initiatives. Choice D is incorrect as constant visits and phone calls from parents may not necessarily reflect the success of the nursing programs.

Correct Answer: B

Rationale: The correct answer is B: Acute glomerulonephritis. Glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys, leading to symptoms like hematuria (blood in urine), proteinuria (excess protein in urine), and hypertension (high blood pressure). Acute tubular necrosis (A) involves damage to the renal tubules, not the glomeruli. Chronic kidney disease (C) refers to long-term kidney damage and may not always present with the classic symptoms mentioned. Nephrotic syndrome (D) involves excessive protein loss in urine but may not always involve inflammation of the glomeruli.

Correct Answer: D

Rationale: The correct answer is D: Tilt the head slightly forward and angle the bottle toward the side of the nostril. This method allows for proper administration of the spray into the nasal passage, ensuring effective delivery of the medication. Tilted head helps direct the spray towards the nasal cavity without causing discomfort or leakage. It also helps prevent the medication from dripping down the back of the throat. Choices A, B, and C are incorrect: A: Finishing instillation in one nostril before moving to the other can lead to uneven distribution of medication and reduced effectiveness. B: Inhaling quickly may cause irritation and discomfort to the mucous membranes due to the forceful intake of the spray. C: Blowing the nose after spraying can expel the medication before it has a chance to be absorbed, decreasing its efficacy.

Correct Answer: D

Rationale: The correct answer is D because informed consent should be obtained from both the participants and their parents to ensure full understanding and agreement from all parties involved. This is crucial when working with minors to protect their rights and ensure ethical standards are met. Choice A is incorrect as it excludes parental consent, which is necessary for minors. Choice B is also incorrect as it neglects the participants' direct involvement in consenting to participate. Choice C is incorrect because it only includes available relatives, which may not be legally authorized to provide consent on behalf of the participants.
