Nurse Joy is caring for a client after a bronchoscopy and biopsy. Which of the following signs, if noticed in the client, should be reported immediately to the physician?

Correct Answer: C

Rationale: The correct answer is C: Bronchospasm. Bronchospasm is a serious complication after a bronchoscopy that can lead to respiratory distress. It requires immediate medical attention to prevent further complications. A dry cough (A) may be expected post-procedure. Hematuria (B) is unrelated to a bronchoscopy. Blood-streaked sputum (D) is common after a biopsy and may not require immediate attention unless it becomes excessive. Reporting bronchospasm promptly is crucial in preventing respiratory compromise.

Correct Answer: A

Rationale: The correct answer is A because the theophylline blood level of 13 mcg/mL is within the therapeutic range (10-20 mcg/mL). Therefore, the next dose should be administered as ordered to maintain therapeutic levels. Choice B is incorrect as skipping doses can lead to subtherapeutic levels. Choice C is unnecessary as the level is within range. Choice D is irrelevant to the theophylline level.

Correct Answer: A

Rationale: The correct answer is A: 21 percent. Air is composed of about 21% oxygen, 78% nitrogen, and small amounts of other gases. This composition is crucial for sustaining life on Earth. Choice B is incorrect as it represents the percentage of nitrogen in the air. Choices C and D are also incorrect as they are the approximate percentages of carbon dioxide and argon in the air, respectively. Therefore, the correct answer is A as it accurately reflects the oxygen content in the air.

Correct Answer: D

Rationale: The correct answer is D because the rate and depth of breathing are controlled by a respiratory center in the brainstem, which includes the medulla and pons. The medulla regulates the basic rhythm of breathing, while the pons helps adjust the rate and depth based on input from chemoreceptors and other factors. Choice A is incorrect because chemoreceptors in arterial walls primarily detect changes in blood pH and CO2 levels, not directly control breathing. Choice B is incorrect as baroreceptors in the diaphragm are more related to detecting stretch and pressure changes, not regulating breathing. Choice C is incorrect as the partial pressure of O2 in the atmosphere does not directly control breathing but rather influences oxygen exchange in the lungs.

Correct Answer: B

Rationale: The correct answer is B, Bucco-pharyngeal cavity. The glottis is the opening between the vocal cords in the larynx, which is located in the upper part of the respiratory tract. The bucco-pharyngeal cavity is the part of the oral cavity that leads to the pharynx, where the glottis is situated. The diaphragm is a muscle separating the thoracic and abdominal cavities, and the trachea is a tube connecting the larynx to the bronchi. Therefore, the glottis is not located in the diaphragm or trachea.
