A nurse is performing a skin assessment on a client who has dark skin.
Which of the following locations on the client’s body should the nurse observe to assess for cyanosis?
Area of trauma.
Sacrum.
Shoulders.
Palms of the hands.
The Correct Answer is D
Cyanosis is a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is more difficult to detect in people who have dark skin, so the nurse should look for cyanosis in areas where the skin is thinner and the blood supply is richer, such as the palms of the hands, the lips, the gums, and around the eyes.
These areas are less affected by melanin, the pigment that gives skin its color.
Choice A is wrong because an area of trauma may have bruising or inflammation that can mask cyanosis.
Choice B is wrong because the sacrum is not a good site to assess for cyanosis in any skin tone, as it is prone to pressure ulcers and poor circulation.
Choice C is wrong because the shoulders are not a mucous membrane and may have more melanin than other areas of the body.

Correct Answer is B
Explanation
The correct answer is choice B. Increase exercise.
Exercise can help stimulate bowel movements and prevent constipation, which is a common side effect of opioid medications.
Exercise can also improve blood circulation, reduce stress, and enhance mood, which can benefit clients who have chronic pain.
Choice A is wrong because decreasing insoluble fiber intake can worsen constipation.
Insoluble fiber adds bulk to the stool and helps it pass more easily through the colon.
Clients who take opioid medications should increase their intake of insoluble fiber from sources such as whole grains, fruits, vegetables, nuts, and seeds.
Choice C is wrong because drinking less water can lead to dehydration and hardening of the stool, which can make it more difficult to pass.
Clients who take opioid medications should drink plenty of water to keep the stool soft and moist.
Choice D is wrong because taking a laxative every day can cause dependence, tolerance, and electrolyte imbalance.
Laxatives should be used only as a last resort and under the guidance of a health care provider.
Clients who take opioid medications should try other methods of preventing constipation first, such as increasing exercise, fiber, and water intake.
Correct Answer is C
Explanation
- . Answer and explanation.
The correct answer is choice C, first-degree atrioventricular block.
This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.
In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.
Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.
There is no constant PR interval in atrial fibrillation.
Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.
There are no consistent P waves or PR intervals in complete heart block.
Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.
They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.
However, they do not cause a constant prolongation of the PR interval.
