Correct Answer: A

Rationale: The FIRST action of the nurse should be to reassess the client experiencing dyspnea despite continuous oxygen therapy. Reassessment would involve checking the client's respiratory status, oxygen saturation levels, vital signs, and overall condition to gather more information about the situation. This will help the nurse identify any potential causes of the dyspnea and determine the appropriate next steps for intervention. Assessing the client before proceeding with any other actions is crucial in providing safe and effective care.

Correct Answer: D

Rationale: When performing an admission assessment, the nurse should expect to find clinical manifestations that are indicative of a variety of conditions. Paresthesia (abnormal sensation like tingling, prickling, or numbness) and muscle weakness of the upper body are commonly associated with neurological conditions such as peripheral neuropathy or cervical radiculopathy. These symptoms suggest dysfunction in the nerves that supply the upper body muscles, leading to sensory changes and weakness. This finding would prompt further assessment and evaluation by healthcare providers to determine the underlying cause and appropriate interventions. Rapid progressive muscular atrophy, ascending paralysis with ataxia, and hyperactive deep tendon reflexes are not typically expected findings during an admission assessment and may signal more specific neurological conditions such as amyotrophic lateral sclerosis, Guillain-Barré syndrome, or spinal cord injury, respectively.

Correct Answer: C

Rationale: Battery occurs when there is an intentional harmful or offensive contact with a person without their consent. In this scenario, Nurse Edna applied a body restraint to the patient without the doctor's order, which constitutes unauthorized physical contact. The patient did not give consent for the restraint, and Nurse Edna's action could be considered battery. It is important for healthcare providers to obtain proper authorization before using any form of physical restraint on a patient to avoid legal implications such as battery.

Correct Answer: C

Rationale: The patient's symptoms of watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip suggest an infection caused by Cryptosporidium parvum. Cryptosporidium is a protozoan parasite that is commonly transmitted through contaminated water sources. Laboratory tests detecting oocysts in the stool sample are characteristic of Cryptosporidium infection.

Correct Answer: C

Rationale: In a conscious trauma patient with a suspected head injury, maintaining cervical spine immobilization is crucial. The presence of a head injury raises concerns for potential concomitant cervical spine injury. Therefore, it is vital to prevent any movement of the cervical spine to avoid exacerbating a potential spinal cord injury. Maintaining immobilization involves stabilizing the patient's head and neck in a neutral position until appropriate imaging studies can assess the extent of any spinal injury. This action helps prevent further harm and ensures the safety of the patient during assessment and management of their injuries.
