Question 1:

A nurse is assessing a pregnant client who complains of back pain.

Which musculoskeletal change during pregnancy is primarily responsible for this symptom?

A. Increased joint laxity. B. Increased spinal curvature C. .Increased muscle strain. D. Decreased muscle strength.

Answer and Explanation

Choice A:

Wrong because increased joint laxity is due to hormonal changes that relax the ligaments and tendons, not the muscles.

Choice B:

During pregnancy, the center of gravity shifts forward as the uterus grows, causing an increased lordosis (inward curvature) of the lumbar spine.

Choice C:

Increased muscle strain is a result of increased spinal curvature, not a cause.

Choice D:

decreased muscle strength is not a musculoskeletal change during pregnancy, but a possible consequence of reduced physical activity or poor nutrition.

Question 2:

A nurse is caring for a pregnant client who is in her third trimester.

Which musculoskeletal change is expected to be at its highest point during this stage?

A. Joint laxity. B. Spinal curvature. C. Muscle strain. D. Muscle strength.

Answer and Explanation

Choice A:

Because joint laxity is not specific to the third trimester of pregnancy. Joint laxity occurs throughout pregnancy due to the effects of relaxin and other hormones on the connective tissue that holds the bones in place.

Choice B:

Spinal curvature is expected to be at its highest point during the third trimester of pregnancy because of the increased weight of the fetus and the relaxation of the ligaments in the pelvic area due to pregnancy hormones. This can cause backaches and discomfort for the pregnant woman.

Choice C:

Because muscle strain is not a musculoskeletal change, but a possible consequence of the changes in posture and balance that occur during pregnancy. Muscle strain can affect any trimester of pregnancy, depending on the physical activity and fitness level of the woman.

Choice D:

muscle strength is not a musculoskeletal change, but a factor that can influence the ability to cope with the changes in weight and posture that occur during pregnancy. Muscle strength can vary depending on the exercise regimen and nutrition of the woman.

Question 3:

A nurse is caring for a pregnant client who is experiencing pelvic pain.

This symptom is primarily caused by:.

A. Increased joint laxity. B. Increased spinal curvature. C. Increased muscle strain. D. Decreased muscle strength.

Answer and Explanation

Choice A:

This is because pelvic pain during pregnancy is typically caused by the release of a hormone called relaxin, which acts by relaxing the hip and pelvic ligaments and joints to make room for the growing baby. This hormone is released in higher quantities during labor to ease the passage of the baby, and it may cause pelvic pain, which resolves after labor.

Choice B:

Increased spinal curvature does not cause pelvic pain, but rather lower back pain.

Choice C:

Increased muscle strain does not cause pelvic pain, but rather round ligament pain, which is a sharp or crampy pain in the lower abdomen or groin area.

Choice D:

Decreased muscle strength does not cause pelvic pain, but rather increases the risk of urinary incontinence and pelvic organ prolapse after delivery.

Question 4:

A nurse is assessing a pregnant client who complains of numbness and tingling in her hands.

This symptom is most likely due to:

A. Increased joint laxity. B. Increased spinal curvature. C. Increased muscle strain. D. Increased muscle strain.

Answer and Explanation

Choice A:

Increased joint laxity is caused by the hormone relaxin, which loosens the ligaments and joints to prepare for childbirth. This can cause pain and instability in the pelvis, hips, and lower back, but not numbness and tingling in the hands.

Choice B:

Increased spinal curvature is a result of the growing uterus and shifting center of gravity, which can cause back pain and posture changes, but not numbness and tingling in the hands.

Choice C:

This symptom is most likely due to carpal tunnel syndrome, which is a common condition in pregnancy caused by fluid retention and swelling in the wrists that compresses the median nerve, which controls feeling and movement in the hand.

Choice D:

Decreased muscle strength is not a common symptom of pregnancy, unless it is due to an underlying condition such as anemia or thyroid problems. Numbness and tingling in the hands can affect grip strength and finger dexterity, but this is a consequence of carpal tunnel syndrome, not a cause.
