The nurse explains isometric exercises to the patient on the rehabilitation unit.
Which explanation provided by the nurse is accurate?

"Move your wrist in a circular motion 5 times every hour.”.

"Squeeze your gluteal muscles tightly 3 times every hour.”.

"Lift a 5-pound weight to increase your arm strength.”.

"Bend your knee up to your chest 4 times each day.”. .

Answer and Explanation

The Correct Answer is B

Choice B rationale:

Isometric exercises involve contracting muscles without changing the length of the muscle or joint angle. In this case, squeezing the gluteal muscles tightly constitutes an isometric exercise. Isometric exercises are often used in rehabilitation settings to strengthen specific muscle groups without putting too much strain on the joints.

Choice A rationale:

Option A describes a range of motion exercise involving the wrist, which is not an isometric exercise. Isometric exercises focus on static muscle contractions, not dynamic movements like circular motions.

Choice C rationale:

Lifting a 5-pound weight to increase arm strength involves isotonic exercise, not isometric exercise. Isotonic exercises involve muscle contractions with movement and changing muscle length, unlike isometric exercises, where muscle length remains constant.

Choice D rationale:

Bending the knee up to the chest is an example of a range of motion exercise and does not constitute an isometric exercise. Range of motion exercises involve moving joints through their full extent, but isometric exercises involve static muscle contractions without joint movement.

Correct Answer is D

Explanation

Choice A rationale:

Telling the patient that their wife will be fine does not address the patient's concerns and may come across as dismissive. It does not encourage further communication about the patient's fears and worries.

Choice B rationale:

Dismissing the patient's concerns and instructing them to sleep does not address the underlying issue. It fails to acknowledge the patient's emotional distress and may make the patient feel unheard and unsupported.

Choice C rationale:

Offering medication without exploring the patient's concerns further does not address the root cause of the patient's anxiety. It is important to assess the patient's emotional state and concerns before resorting to medication.

Choice D rationale:

Asking the patient, "What seems to be concerning you the most?" demonstrates active listening and empathy. It encourages the patient to express their feelings and fears, allowing the nurse to provide appropriate emotional support and interventions. Open-ended questions like this facilitate therapeutic communication and help establish trust between the nurse and the patient.

A. Decreased respiratory rate due to lungs becoming stronger. B. Increased urinary output due to enhanced bladder muscle tone. C. Atrophy of leg muscles due to immobility. D. Frequent bowel movement due to increased peristalsis.

Correct Answer is C

Explanation

Choice C rationale:

When a patient has been bedridden for an extended period, such as two weeks, the nurse expects to find atrophy of leg muscles due to immobility. Lack of physical activity leads to muscle wasting, which can result in decreased muscle mass and strength. This condition is reversible with proper rehabilitation and exercise.

Choice A rationale:

Decreased respiratory rate due to stronger lungs is not a typical effect of immobility. Immobility can lead to decreased lung expansion and increased risk of respiratory complications, such as pneumonia.

Choice B rationale:

Increased urinary output due to enhanced bladder muscle tone is not a direct effect of immobility. Immobility can affect urinary elimination, but it is more likely to cause urinary retention due to decreased mobility and inability to reach the bathroom independently.

Choice D rationale:

Frequent bowel movements due to increased peristalsis are not expected with immobility. Immobility often leads to slowed peristalsis, which can result in constipation rather than frequent bowel movements.
