A client has returned to the coronary care unit after having a coronary angiogram. Which assessment data indicate the need for immediate action by the nurse?
- A. Diminished pedal pulse volume
- B. Heart rate 100 beats/min
- C. Blood pressure 104/60 mm Hg
- D. Capillary refill less than 3 seconds
Correct Answer: A
Rationale: The correct answer is A: Diminished pedal pulse volume. This indicates potential circulation compromise, which can lead to ischemia or impaired tissue perfusion. Immediate action is required to prevent further complications. B: Heart rate 100 beats/min is within normal range. C: Blood pressure 104/60 mm Hg is slightly low but not critically concerning. D: Capillary refill less than 3 seconds indicates good peripheral perfusion.

The left lung has two lobes and they are separated by Deep fissure called .
- A. horizontal fissure
- B. oblique fissure
- C. Vertical fissure
- D. non of them
Correct Answer: B
Rationale: The correct answer is B: oblique fissure. The left lung has two lobes, the upper lobe and the lower lobe, which are separated by the oblique fissure. This fissure extends obliquely downward and forward from the posterior border of the lung.
Rationale:
1. The horizontal fissure separates the right lung into upper and middle lobes, not the left lung.
2. There is no such structure as a vertical fissure in the human lung anatomy.
3. "Non of them" is grammatically incorrect and does not provide a valid option.
Diaphragm is supplied with Phrenic nerve and is involved in
- A. Inspiration
- B. Parturition
- C. Micturition and Defecation
- D. All these
Correct Answer: D
Rationale: The correct answer is D: All these. The phrenic nerve innervates the diaphragm, which is responsible for inspiration (A). During parturition (B), the diaphragm plays a role in the pushing phase of labor. While the diaphragm is not directly involved in micturition and defecation (C), it indirectly affects these processes by helping to create intra-abdominal pressure. Therefore, the correct answer is D as the diaphragm is involved in inspiration, parturition, and indirectly affects micturition and defecation.
In describing the parts of the respiratory system, the word 'septum' designates a partition in the
- A. larynx.
- B. nasal cavities.
- C. pharynx.
- D. glottis.
Correct Answer: B
Rationale: The correct answer is B: nasal cavities. The term "septum" refers to a partition or dividing wall that separates two cavities. In the context of the respiratory system, the nasal septum divides the nasal cavities into left and right sides. This separation helps to regulate airflow and also provides structural support for the nasal passages.
Other choices are incorrect because:
A: The larynx is not typically associated with a septum. It is primarily responsible for vocalization and protecting the airway.
C: The pharynx is a passageway for air and food, but it does not contain a septum dividing it into distinct sections.
D: The glottis is the space between the vocal cords in the larynx and does not have a septum separating it into parts.
The nasal conchae epithelial surface serves to:
- A. Warm and moisten inhaled air, via air turbulence.
- B. Help filter dust and insects from the inhaled air
- C. Recapture moisture from exhaled air to preserve fluid.
- D. All of the above are correct.
Correct Answer: D
Rationale: Rationale: The nasal conchae increase surface area, causing air turbulence to warm, moisten, and filter inhaled air. This helps in preventing respiratory issues. Choice A is correct as it explains the primary function of the conchae. Choice B is incorrect as the primary function is not filtering. Choice C is incorrect as the conchae primarily warm and moisten inhaled air rather than recapture moisture from exhaled air. Overall, choice D is correct as it encompasses all the functions of the nasal conchae.
Which of the following sinuses are located on either side of the nose?
- A. Ethmoidal sinuses
- B. Frontal sinuses
- C. Maxillary sinuses
- D. Sphenoidal sinuses
Correct Answer: C
Rationale: The correct answer is C. The maxillary sinuses are paired cavities located on either side of the nose, beneath the orbits. Ethmoidal sinuses (A) are smaller and located between the eyes. Frontal sinuses (B) are above the eyebrows. Sphenoidal sinuses (D) are deeper within the skull, behind the nasal cavity.
