Exam Cram NCLEX RN Practice Questions

1. When counting an infant's respirations, which technique is correct?

Correct answer: B

Rationale: The correct technique for counting an infant's respirations is to observe the movement of the abdomen. Infants typically have more diaphragmatic breathing than thoracic, so watching the abdomen provides a more accurate count. Placing a hand on the chest or listening with a stethoscope can alter the infant's breathing pattern and provide inaccurate results. Therefore, options A, C, and D are incorrect methods for counting an infant's respirations. By observing the movement of the abdomen, healthcare providers can accurately assess an infant's respiratory rate without influencing their breathing pattern.

2. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?

Correct answer: D

Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.

3. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

4. A client has died approximately one hour ago. The nurse notes that the client's temperature has decreased in the last hour since their death. Which of the following processes explains this phenomenon?

Correct answer: C

Rationale: Algor mortis occurs after death when the body's circulation stops, and the client's temperature begins to fall. The client's temperature will drop by approximately 1.8 degrees per hour until it reaches room temperature. During algor mortis, the client's skin gradually loses its elasticity. Rigor mortis refers to the stiffening of the body after death due to chemical changes in the muscles. Postmortem decomposition is the breakdown of tissues after death. Livor mortis is the pooling of blood in the dependent parts of the body, causing a purple-red discoloration.

5. A healthcare professional is preparing to administer a dose of platelets to a client. Which of the following actions must the healthcare professional perform before giving the platelets?

Correct answer: B

Rationale: Before administering platelets, it is crucial to check the integrity of the container holding the blood product. An intact container ensures the sterility and safety of the platelets, minimizing the risk of contamination or infection. Option A is incorrect as administering platelets typically does not require starting a new IV line unless indicated for the specific patient. Option C is not the priority as verifying the client's identity can be done at any point during the administration process but is not specific to the platelet transfusion itself. Option D, checking the client's chart for antibiotic use, is not directly related to ensuring the safety of the blood product container.
