A nurse is reinforcing teaching with a client who is at 10 weeks of gestation regarding the purposes of laboratory tests. Which of the following statements by the client indicates an understanding of the teaching?
"White blood cell count is an indicator of anemia.”
"Urine specific gravity identifies my risk for pregnancy induced hypertension.”
"Platelet count identifies if I am at risk for bleeding.”
"Sedimentation rate checks for signs of cancer.”
The Correct Answer is C
(A) "White blood cell count is an indicator of anemia.”
White blood cell count is not directly related to anemia. Anemia is typically assessed by hemoglobin and hematocrit levels, which reflect the oxygen-carrying capacity of the blood. White blood cell count measures immune system function and can indicate infection or inflammation rather than anemia.
(B) "Urine specific gravity identifies my risk for pregnancy induced hypertension.”
Urine specific gravity is a measure of urine concentration and hydration status, and it is not typically used to identify the risk of pregnancy-induced hypertension (preeclampsia). Preeclampsia is diagnosed based on symptoms such as hypertension (high blood pressure) and proteinuria (protein in the urine), along with other criteria.
(C) "Platelet count identifies if I am at risk for bleeding.”
Platelet count is a laboratory test that measures the number of platelets in the blood. Platelets are essential for blood clotting, so a low platelet count (thrombocytopenia) can indicate an increased risk of bleeding, which is pertinent to pregnancy, especially in cases of conditions like gestational thrombocytopenia or preeclampsia.
(D) "Sedimentation rate checks for signs of cancer.”
The sedimentation rate (ESR or sed rate) is a nonspecific test that measures inflammation in the body, but it is not used to check for signs of cancer specifically. Elevated sedimentation rate can indicate various inflammatory conditions such as infection, autoimmune diseases, or chronic inflammatory disorders. It is not a primary test for cancer diagnosis.

Correct Answer is D
Explanation
(a) Pedal edema
Pedal edema, or swelling of the feet and ankles, is a common finding during pregnancy due to increased fluid retention and pressure on the lower extremities from the growing uterus. While pedal edema should be monitored, it is not typically a concerning finding unless it is severe or accompanied by other symptoms suggestive of preeclampsia.
(b) BP of 132/84 mm Hg
A blood pressure of 132/84 mm Hg is within the normal range for pregnancy. However, if the client's blood pressure continues to increase or is accompanied by other symptoms of hypertension, such as proteinuria or headaches, it may warrant further evaluation.
(c) Weight gain of 1 kg (2.2 lb)
Weight gain during pregnancy is expected and can vary from person to person and from week to week. A weight gain of 1 kg (2.2 lb) over the course of a month is within the normal range for pregnancy and may not require immediate reporting to the provider unless there are other concerning symptoms.
(d) Double vision
Double vision (diplopia) can be a symptom of several conditions, including preeclampsia, which is a serious complication of pregnancy characterized by high blood pressure and proteinuria. Double vision can also be caused by other neurological or ophthalmologic conditions. Given its potential association with preeclampsia and other serious conditions, the nurse should promptly report double vision to the provider for further evaluation and management.
Correct Answer is D
Explanation
(a) "I should place my baby in the car seat at a 90-degree angle."
The baby should not be placed in the car seat at a 90-degree angle. Instead, the car seat should be reclined at a 30- to 45-degree angle to keep the baby's airway open and reduce the risk of suffocation.
(b) "I will place a thick, soft pad behind my baby's back."
Using a thick, soft pad behind the baby’s back is not recommended because it can interfere with the harness system and compromise the safety of the car seat. Only products that come with the car seat or are specifically designed for it should be used.
(c) "I can turn the car seat so it faces forward when my baby weighs 15 pounds."
The car seat should remain rear-facing until the child reaches the maximum weight or height limit allowed by the car seat manufacturer, which is typically around 2 years of age or longer. Turning the car seat to face forward at just 15 pounds is too early and not safe.
(d) "I will place the retainer clip at the level of my baby's armpits."
This is correct. The retainer clip should be positioned at the level of the baby's armpits. This placement ensures that the harness straps are properly positioned over the baby's shoulders and chest, providing optimal protection in the event of a crash.
