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: 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: 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: C

Rationale: The correct answer is C: Systematic sampling. Nurse Sandy is adopting systematic sampling by selecting every third patient with MI after a random start. This method ensures equal chance of selection for each patient and maintains randomness. In contrast, simple random sampling (A) entails each patient having an equal chance of being selected independently. Stratified sampling (B) divides patients into groups based on certain characteristics, which is not the case here. Cluster sampling (D) involves grouping patients and selecting entire groups, which is different from the individual selection in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Group A beta-hemolytic Streptococcus (GAS). GAS is the most likely organism responsible for this presentation, known as acute bacterial tonsillitis. GAS commonly causes symptoms such as throat pain, odynophagia, fever, tonsillar enlargement with exudates, and cervical lymphadenopathy. Streptococcal pharyngitis is a common bacterial infection of the throat caused by GAS. The other options are less likely as Streptococcus pneumoniae typically causes pneumonia and Haemophilus influenzae is associated with respiratory tract infections. Epstein-Barr virus (EBV) commonly causes infectious mononucleosis, which presents with different symptoms than those described in the question.

Correct Answer: D

Rationale: The correct answer is D because Nurse Florence was asked why she requested permission to enroll in the Graduate Program for the second semester, not about her interest in Pediatric Nursing. A: Having an impressive resume to be competitive aligns with career advancement. B: Connecting with people professionally can lead to networking opportunities. C: Investing for the future implies long-term career growth. Therefore, D is the least relevant response to the question asked.

Correct Answer: B

Rationale: The correct answer is B: establish a credit body of evidence to support and improve the delivery of care. Conducting research in nursing aims to generate a robust evidence base to inform and enhance the quality of care provided to patients. This evidence helps in identifying best practices, improving patient outcomes, and advancing the nursing profession as a whole. Choice A is incorrect because the main goal of research is not to solely justify the role of nurses, but rather to improve care delivery. Choice C is incorrect as the goal is not to justify an oversupply of nurses, but to address healthcare needs effectively. Choice D is incorrect because the focus of nursing research is on nursing-related issues, not non-nursing problems.

Correct Answer: A

Rationale: The correct answer is A: Central retinal artery occlusion. This condition presents with sudden-onset, painless vision loss, cherry-red spot at the macula due to lack of blood flow, and attenuated retinal vessels. The cherry-red spot is due to the transparency of the fovea when there is ischemia in the surrounding retina. Central retinal vein occlusion (B) presents with sudden vision loss accompanied by retinal hemorrhages and dilated tortuous veins. Retinal detachment (C) typically presents with sudden flashes, floaters, and a curtain-like visual field defect. Acute angle-closure glaucoma (D) presents with severe eye pain, blurred vision, halos around lights, and a fixed mid-dilated pupil.

Correct Answer: D

Rationale: The correct answer is D because interprofessional collaboration and multidisciplinary collaboration are not interchangeable terms. Interprofessional collaboration involves professionals from different disciplines working together to provide comprehensive care, while multidisciplinary collaboration involves professionals from various disciplines working alongside each other but not necessarily working together in a coordinated manner. This distinction is crucial in healthcare settings to ensure effective teamwork and patient-centered care. A: Trust and respect are core values of a collaborative organization - This statement is correct because trust and respect are essential for effective collaboration in healthcare settings. B: A shared vision is essential for collaboration in any health care operations - This statement is correct as a shared vision helps align team members towards common goals. C: Successful conflict resolution can help collaborative teams overcome differences - This statement is correct as resolving conflicts constructively can strengthen team dynamics and improve collaboration.
