During a surgical procedure, the nurse notices a sudden decrease in the patient's oxygen saturation on the monitor. What immediate action should the nurse take?

Correct Answer: A

Rationale: The correct immediate action is to inform the surgeon and anesthesiologist (Choice A) because a sudden decrease in oxygen saturation during surgery is a critical situation that requires prompt attention from the entire surgical team. The surgeon and anesthesiologist need to be made aware of the situation so that they can assess the patient's condition and make any necessary adjustments to the surgical procedure or anesthesia delivery. Increasing the flow rate of oxygen (Choice B) may help temporarily but does not address the underlying cause of the oxygen desaturation. Checking the endotracheal tube placement (Choice C) is important but may not be the immediate priority in this critical situation. Assessing the patient's respiratory status (Choice D) is important but should be done after informing the surgeon and anesthesiologist to ensure coordinated and timely interventions.

Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. SSRI medications can lead to the syndrome of inappropriate antidiuretic hormone secretion (SIADH), causing hyponatremia. This occurs due to increased levels of serotonin affecting the hypothalamus, leading to excessive ADH release. Hyponatremia can result in neurological symptoms and must be closely monitored. A: Bradycardia is not a common adverse effect of SSRIs. B: Hyperkalemia is not typically associated with SSRIs. D: Hypertension is not a common adverse effect of SSRIs; they may actually lower blood pressure.

Correct Answer: D

Rationale: The correct answer is D: Osteoporosis. Long-term use of inhaled corticosteroids can lead to decreased bone density and an increased risk of osteoporosis. Corticosteroids can interfere with calcium absorption and bone formation, resulting in bone weakening. Oral thrush (Choice A) is a common side effect of inhaled corticosteroids, but it is not associated with long-term use. Hypertension (Choice B) and hyperglycemia (Choice C) are more commonly seen with systemic corticosteroid use rather than inhaled corticosteroids.

Correct Answer: D

Rationale: The correct answer is D, Broad opening. Nurse Rica should use this communication technique to encourage the patient to freely express themselves without leading or interrupting. This technique helps build rapport and trust, setting a positive tone for the conversation. A: Clarifying may be too direct and might make the patient feel pressured. B: Challenging can create defensiveness and hinder open communication. C: Restating may not be as effective in initiating a conversation as broad opening. In summary, broad opening allows for a more open and relaxed conversation, fostering a conducive environment for effective communication with the patient.

Correct Answer: C

Rationale: The correct answer is C: Cryptosporidium parvum. This parasite is the most likely cause of the infection due to its presentation with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water. Laboratory tests revealing oocysts in the stool sample further support this diagnosis as Cryptosporidium parvum is known to produce oocysts in the stool. Giardia lamblia (choice A) presents with similar symptoms but does not typically produce oocysts. Entamoeba histolytica (choice B) is more associated with bloody diarrhea and liver abscesses. Cyclospora cayetanensis (choice D) is also associated with watery diarrhea but is less common in this scenario. Thus, based on the symptoms and laboratory findings, Cryptosporidium parvum is the most likely culprit.

Correct Answer: A

Rationale: The correct answer is A: battery. Battery is the intentional and unwanted touching of another person without their consent, which can include medical treatment without consent. This is a clear violation of the patient's autonomy and can lead to legal consequences. Negligence (B) is the failure to exercise reasonable care, not intentional touching. Slander (C) is making false spoken statements that harm someone's reputation. Tort (D) is a broader term referring to civil wrongs, including battery, but not specifically addressing intentional and unwanted touching.

Correct Answer: C

Rationale: The most appropriate nursing action in this situation is to notify the healthcare provider immediately. The client presenting with persistent, severe perineal pain and swelling, along with ecchymosis and tenderness of the perineum, could be indicative of complications such as a perineal hematoma. A perineal hematoma is a collection of blood in the perineal tissues and can be a serious postpartum complication requiring prompt medical attention. Therefore, it is crucial to alert the healthcare provider so that appropriate assessment, management, and treatment can be initiated promptly. Applying ice packs or encouraging the client to sit on a donut cushion may not be sufficient in this situation, and administering additional analgesic medication should be done only after the healthcare provider has assessed and determined the cause of the symptoms.

Correct Answer: C

Rationale: In a postpartum client who presents with severe abdominal pain, nausea, and vomiting, it is crucial to assess for signs of peritonitis or surgical abdomen. These signs may include rebound tenderness, guarding, rigidity, and fever. Peritonitis is a serious condition that may require immediate surgical intervention. Administering antiemetic medication, encouraging clear fluids, or providing a heating pad may not address the underlying cause of the symptoms and delay appropriate treatment. Assessing for signs of peritonitis or surgical abdomen is crucial for prompt identification and management of the client's condition.

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.
