An astronaut Captain Fallowell is a 62-year-old male. He spent the last 8 months in the international space station. The captain passed out in the middle of the speech during his first speaking engagement. He is very alert and oriented man. The captain noticed that his pulse rate was racing down during the speech and his blood pressure was different when he was lying down and standing. The reflexes of the Captain were normal and he showed no sign of any kind of trauma. Characters in the case: Captain Fallowell. Adequate information: The Captain’s heart rate was 85 beats per minute. His pulse was very weak and his blood pressure was recorded at 116/66 mm Hg (millimeters of mercury) when he was lying down. His heart beats and blood pressure was 112 beats per minute and 94/52 mm Hg, respectively, in the standing position. To determine: The effect of more circulating blood on the following: a. renin levels, b. aldosterone levels, c. ADH (Antidiuretic hormone) levels, d. thirst, e. atrial natriuretic peptide, f. urine volume, and g. the blood volume.

Matt, a 54-year-old roofer, just fell 12 metres from a building under construction. Initially he struck the ground with his feet, then fell onto his left side. Conscious and alert at the scene, he complains of severe back and lower leg pain.His vital signs: Blood Pressure- 140/88 mmHg; Heart Rate- 112 bpm; Respiratory Rate- 28 bpm; SaO2- 96% on Room Air; and Temperature- 36.7⁰C. His Glasgow Coma Scale (GCS) score is 15.Paramedics administer oxygen at a flow rate of 15 litres/minute via Non-Rebreather Mask and apply a cervical collar and a backboard to immobilise his neck and spine. They also place a 16-gauge Peripheral Intravenous Canula (PIVC) in his left forearm and begin an infusion of 0.9% Sodium Chloride solution.When Matt is brought into Emergency Department (ED), he can speak clearly and provide an account of the accident.Identify the nursing assessments with rationales that should be provided in the first hour upon receiving Matt from the paramedics
