A client has the following blood lab values: platelets 50,000/ul, RBC's 3.5 (X 106), hemoglobin 10 g/dl, hematocrit 30 percent, WBCs 10,000/ul. Which nursing instruction should be included in the teaching plan?

Correct Answer: A

Rationale: The client's platelet count of 50,000/ul is significantly low (normal range is around 150,000-450,000/ul). A low platelet count places the client at risk for bleeding tendencies. Therefore, the most appropriate nursing instruction to include in the teaching plan is bleeding precautions. This would involve educating the client on measures to prevent bleeding such as avoiding activities that may cause injury, using a soft toothbrush, avoiding tight clothing, and being cautious while shaving.

Correct Answer: E

Rationale: Spitz nevus is a benign mimic of melanoma and does not raise suspicion.

Correct Answer: B

Rationale: Strabismus, or misalignment of the eyes, is a common condition in newborns due to the lack of binocularity. Binocularity refers to the ability of both eyes to focus simultaneously on a single point, which is not fully developed in newborns. As a result, it is normal for a newborn's eyes to appear misaligned at times. This lack of coordination between the eyes typically resolves as the infant's visual system matures and they develop the ability to focus both eyes together. Therefore, the presence of strabismus in a newborn is usually considered a normal finding related to the immature visual development rather than a sign of pathology such as congenital cataracts, absence of red reflex, or pupil reactivity issues.

Correct Answer: C

Rationale: The nurse instructs the client to avoid Valsalva maneuvers because the client may suffer from a myocardial infarction. The Valsalva maneuver involves forcefully trying to exhale against a closed airway, which can increase intra-thoracic pressure and subsequently increase blood pressure. This can lead to an increased workload on the heart, potentially causing myocardial ischemia or infarction in individuals with underlying heart conditions. Therefore, it is important to avoid Valsalva maneuvers, especially in clients at risk for cardiovascular issues.

Correct Answer: A

Rationale: The medulla oblongata, located in the brainstem, is responsible for controlling essential autonomic functions such as breathing, heart rate, and blood pressure. Specifically, the medulla regulates the rhythm and depth of breathing by sending signals to the respiratory muscles, including the diaphragm and intercostal muscles. In response to changing levels of oxygen and carbon dioxide in the blood, the medulla adjusts the breathing rate to maintain proper oxygenation of the body tissues. Damage to the medulla can result in respiratory failure, highlighting its critical role in controlling breathing.
