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: Muscle pain or weakness. Statins can cause muscle-related side effects, including rhabdomyolysis, a severe condition that can lead to muscle pain and weakness. Monitoring for these symptoms is crucial to prevent serious complications. B: Dry cough is not a common side effect of statins. C: Hypertension is not directly associated with statin use. D: Hyperkalemia is not a typical adverse effect of statins.

Correct Answer: D

Rationale: The correct answer is D: Atropine. Atropine is a mydriatic agent that can exacerbate acute angle closure glaucoma by dilating the pupil and potentially worsening the condition. The nurse should discuss with the attending physician before administering it to avoid worsening the patient's condition. A: Isopto carpine eye drops are actually used in the treatment of acute angle closure glaucoma as they help in lowering intraocular pressure, so there is no need to discuss this with the physician. B: Mannitol is used as an osmotic diuretic to reduce intraocular pressure in acute angle closure glaucoma, and it does not directly affect the pupil, so it does not require discussion with the physician before administration. C: Corticosporin ophthalmic is a combination of an antibiotic and a corticosteroid used to treat eye infections and inflammation, but it does not have a direct effect on worsening acute angle closure glaucoma, so it does

Correct Answer: B

Rationale: The correct answer is B: Cleanse the bite with soap and running water. This is the first nursing intervention because it is crucial to prevent infection. Cleaning the bite area helps remove bacteria and debris, reducing the risk of infection. Injecting with rabies immune globulin (choice A) and rabies vaccine (choice C) should be done later as per protocol after assessing the situation. Administering pain reliever (choice D) is important but not the first priority in this scenario.

Correct Answer: B

Rationale: The primary goal of CPR is to restore spontaneous circulation and oxygenation to the body to maintain vital organ function. By performing chest compressions and rescue breaths, CPR aims to circulate oxygenated blood to the brain and other vital organs. This is crucial to prevent brain damage and increase the chances of survival. The other choices are incorrect because CPR does not address the underlying cause of cardiac arrest (A), provide pain relief (C), or prevent further complications such as organ failure (D). The immediate focus in a cardiac arrest situation is to maintain blood flow and oxygen delivery to vital organs until advanced medical care can be provided.
