Nokea
Which of the following conditions may cause an increased respiratory rate?
- A. Stooped posture
- B. Narcotic analgesics
- C. Injury to the brain stem
- D. Anemia
Correct Answer: D
Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen.
Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.

The nurse provides home care instructions to a client diagnosed with cancer who has an implanted vascular access port. Which statement by the client indicates the need for further teaching?
- A. I should keep the site clean and dry.
- B. If the site becomes red, I will notify my doctor.
- C. I should pump the port daily to maintain patency.
- D. The port will need to be flushed with saline to maintain patency.
Correct Answer: C
Rationale: Implanted vascular access ports do not require daily pumping to maintain patency; this is incorrect. Keeping the site clean and dry, notifying the doctor about redness, and flushing with saline (or heparin, per agency protocol) are correct care measures.
The nurse is instructing a pregnant client regarding measures to prevent a recurrent episode of preterm labor. Which statement by the client indicates the need for further teaching?
- A. I will report any feeling of pelvic pressure.
- B. I will not engage in sexual intercourse at this time.
- C. I will adhere to the limitations in activity and stay off my feet.
- D. I will limit my fluid intake to three 8-ounce glasses of fluid per day.
Correct Answer: D
Rationale: Risks for preterm labor include dehydration. A client should not restrict fluids (except for those containing alcohol and caffeine). A sign of preterm labor may be pelvic pressure without the perception of a contraction. Mechanical stimulation of the cervix during intercourse can stimulate contractions. A decrease in activity and bed rest are often prescribed in an attempt to decrease pressure on the cervix and to increase uterine blood flow.
The nurse has taught a client with a below-the-knee amputation about home care and about monitoring for and preventing complications related to prosthesis and residual limb care. The nurse determines that the client has understood the instructions if the client stated that which action should be taken?
- A. Wear a clean nylon sock over the residual limb every day.
- B. Use a mirror to inspect all areas of the residual limb each day.
- C. Toughen the skin of the residual limb by rubbing it with alcohol.
- D. Prevent cracking of the skin of the residual limb by applying lotion daily.
Correct Answer: B
Rationale: The client should inspect all surfaces of the residual limb daily for irritation, blisters, and breakdown. The client should wear a clean woolen (not nylon) sock each day. The residual limb is cleansed daily with a gentle soap and water and dried carefully. Alcohol is avoided because it could cause drying or cracking of the skin. Oils and creams are also avoided because they are too softening to the skin for safe prosthesis use.
Which of the following situations warrants a measurement for orthostatic hypotension?
- A. A 36-year-old male with a spinal injury
- B. An 86-year-old female with significantly altered mental status
- C. A 58-year-old female with near-syncope
- D. A 41-year-old male with acute deep vein thrombosis
Correct Answer: C
Rationale: The correct answer is a 58-year-old female with near-syncope. Orthostatic hypotension is a drop in blood pressure of greater than 20 mmHg systolic when moving from a sitting or lying position to standing. Patients at higher risk include those with syncope or near-syncope, symptomatic hypovolemia, and those prone to falls. The other choices are less likely to present with orthostatic hypotension. A spinal injury, altered mental status, and acute deep vein thrombosis are not directly associated with the immediate need for orthostatic hypotension measurement.
A client with a broken femur is in a traction splint in bed. Which of the following interventions is NOT part of caring for this client?
- A. Palpating the temperature of both feet
- B. Evaluating pulses bilaterally
- C. Turning the client to a side-lying position
- D. Relieving heel pressure by placing a pillow under the foot
Correct Answer: C
Rationale: When caring for a client with a broken femur in a traction splint, turning the client to a side-lying position is not recommended. This client is at risk of skin breakdown and complications due to the injury, making it important to prevent unnecessary movement that may increase the risk of injury or discomfort. Palpating the temperature of both feet helps in assessing circulation, evaluating pulses bilaterally ensures perfusion to the extremities, and relieving heel pressure by placing a pillow under the foot helps in reducing pressure points and preventing complications like pressure ulcers. Therefore, the correct answer is turning the client to a side-lying position as it is not a recommended intervention in this scenario.
